Where Are My Eggs?-Part 1

Show Notes
Transcript

In this episode of the Poultry Keepers Podcast, Mandelyn, John, and Rip discuss various factors that affect egg production in hens.

They explore the role of breed, daylight hours, weather stress, and artificial lighting in influencing the number of eggs laid. The hosts provide insights into managing and optimizing egg production, including the impact of early sexual maturity on lifespan egg yield and bird health.

They also touch upon the importance of selecting the right breeds based on egg-laying goals and delve into specific considerations for both production-focused and dual-purpose breeds.

00:00:00.029 --> 00:00:02.129
Welcome to the Poultry Keepers Podcast.

00:00:02.729 --> 00:00:09.779
In this episode Mandelyn, John, and Rip will help you understand why you don't always get the number of eggs you were expecting from your flock.

00:00:10.210 --> 00:00:11.660
So, lets get started.

00:00:22.006 --> 00:00:26.620
Today, we're going to be shedding light on Where are my eggs?

00:00:27.420 --> 00:00:30.471
So stay tuned and we'll explain it all coming right up.

00:00:30.471 --> 00:00:32.914
So Mandelyn, let's start off.

00:00:33.064 --> 00:00:37.715
First year layers commonly lay through their first winter, depending on their breed and productivity.

00:00:37.954 --> 00:00:38.984
What's your thoughts on that?

00:00:39.784 --> 00:00:48.945
It does boil down to what they were bred to withstand and to be productive through things such as reduced daylight hours.

00:00:49.409 --> 00:00:59.789
So as soon as we start losing those summertime hours and we get into those winter light phases, a seasonal laying bird is gonna stop laying.

00:00:59.789 --> 00:01:07.579
That's her body's response to the light saying, it's winter, you're not hatching babies, that means you're not laying.

00:01:08.209 --> 00:01:14.689
So if you look at all of our wild species out there, they're gonna start laying when those daylight hours start picking up.

00:01:15.000 --> 00:01:21.805
That's when you hear the bird song and the mating dances and everything, so that by April, or so, depending on your zone.

00:01:22.055 --> 00:01:25.275
Those birds have already built a nest and they're already starting to lay.

00:01:25.745 --> 00:01:28.924
But for chickens, we want to see eggs year round.

00:01:29.265 --> 00:01:35.265
And so that's where we go into our production breeding, and parts of that are going to be light driven.

00:01:36.064 --> 00:01:36.775
Definitely.

00:01:37.385 --> 00:01:47.094
And also for hatching, a lot of people like to do hatching in the fall for spring replacements, and especially for spring point of lay pullet sales.

00:01:47.545 --> 00:01:52.200
To have an 18 week old Pullet, ready for sale, 1st of April.

00:01:52.480 --> 00:01:54.930
You're perfectly positioned in the market around here.

00:01:55.319 --> 00:01:57.200
And to do that, we need to backtrack.

00:01:57.200 --> 00:02:09.740
So that means, we're setting and hatching in late fall, early winter to hit that date, which is not when our chickens are naturally going to be cooperating with that process without a little extra incentives.

00:02:10.150 --> 00:02:11.000
Exactly right.

00:02:11.500 --> 00:02:18.740
In show poultry We try to time hatches to meet certain particular shows we want to go to for that year.

00:02:19.379 --> 00:02:21.710
And that means, when's the show date?

00:02:21.710 --> 00:02:25.360
We gotta backtrack however many months it takes a female to get mature.

00:02:25.849 --> 00:02:27.409
And that's when we need to hatch.

00:02:27.520 --> 00:02:31.830
And that, that can give us some pretty weird hatching dates sometimes.

00:02:32.629 --> 00:02:36.349
And there's really no way to overcome it without artificial lighting.

00:02:36.699 --> 00:02:39.949
And that's a big key what we're going to be talking about tonight.

00:02:40.379 --> 00:02:40.789
That's right.

00:02:41.069 --> 00:02:42.699
Or today, sometime.

00:02:43.500 --> 00:02:47.379
What about, and y'all probably have to deal with this more than I do.

00:02:48.180 --> 00:02:49.870
What about weather stress?

00:02:50.669 --> 00:02:52.469
Cold weather, severe storms.

00:02:53.199 --> 00:02:57.090
Can that cause a pause in egg production?

00:02:57.889 --> 00:02:58.759
Oh, days or weeks.

00:02:58.759 --> 00:02:59.680
Man, yeah.

00:03:00.039 --> 00:03:00.590
Yeah.

00:03:01.389 --> 00:03:02.770
John, what happens when you get a

00:03:02.770 --> 00:03:03.560
big blizzard?

00:03:03.719 --> 00:03:05.280
Do they turn off for a moment?

00:03:06.080 --> 00:03:10.370
They'll go, I say, go dry for a couple of days at a time.

00:03:10.639 --> 00:03:19.430
They seem to know like my arthritic knee and now ankle knows a day or two in advance, and they'll start to not lay.

00:03:19.969 --> 00:03:22.379
That's, it's pretty interesting.

00:03:22.379 --> 00:03:27.490
I think they're very sensitive to barometric pressure changes Us older folks are

00:03:28.289 --> 00:03:30.030
no comment on the older folks.

00:03:30.030 --> 00:03:30.349
Okay.

00:03:31.150 --> 00:03:38.280
It's if I go out and there's no eggs or there's just one or two, I've got two rock stars.

00:03:38.280 --> 00:03:39.360
They just lay no matter what.

00:03:39.400 --> 00:03:43.889
And those are the chickens that I'm going to be collecting from to set for replacements.

00:03:43.949 --> 00:03:45.129
The other ones are breakfast eggs.

00:03:45.930 --> 00:03:46.210
Correct.

00:03:46.259 --> 00:03:48.900
But that's a good harbinger of weather.

00:03:48.909 --> 00:03:50.710
There's a lot of old folklore.

00:03:51.414 --> 00:04:06.715
Surrounding this, or we call it indigenous knowledge, or fairy tales, whatever you want to call it but there's a lot of truth to these things animals, cows will dry up, chickens will stop laying, harbingers of misfortune or bad weather.

00:04:07.514 --> 00:04:14.284
Anytime I go out to my barn, if I don't see any eggs, my mind immediately goes to what happened.

00:04:15.085 --> 00:04:18.004
It's either a predator at three o'clock at night, sniffing around.

00:04:18.345 --> 00:04:18.704
Yup.

00:04:19.024 --> 00:04:22.074
There's, they're so sensitive to so many different things.

00:04:22.084 --> 00:04:32.175
And if you don't have them on camera, you can find yourself going through little rabbit holes, trying to figure out why you didn't see as many eggs as what you were anticipating.

00:04:32.675 --> 00:04:35.425
And if it only lasts a day or three, okay, fine.

00:04:35.425 --> 00:04:38.305
If it starts dragging into multiple weeks, that's where.

00:04:38.600 --> 00:04:43.240
I'm really trying to dig in and find out what happened.

00:04:43.600 --> 00:04:45.060
Where did my eggs go?

00:04:45.790 --> 00:04:50.939
Yeah, it can be something as simple as a mouse is finding its way in and, upsetting the chickens in the middle of the night.

00:04:51.540 --> 00:04:54.180
If they don't feel it's safe to lay, they're not going to.

00:04:54.980 --> 00:05:00.670
I don't think a lot of folks realize just how little it takes to stress our chickens.

00:05:01.470 --> 00:05:05.360
They're a lot more sensitive than so many folks realize.

00:05:06.055 --> 00:05:08.464
It doesn't take much to throw them off their laying game.

00:05:08.935 --> 00:05:18.454
Now, before we went, before we started recording this, I was talking with you guys about the weather differences.

00:05:18.615 --> 00:05:23.675
And, Mandelyn's got snow, John's not quite got snow, but it's coming.

00:05:24.225 --> 00:05:26.105
And I'm sitting down here in sunny Florida.

00:05:26.680 --> 00:05:42.910
It was 45 degrees this morning, so I don't have quite the weather impacts that you guys do, but I have the other impacts, the predators, bad weather, whatever, but just not the cold weather, so I'm much more fortunate than you guys are.

00:05:43.550 --> 00:05:48.720
Luckily, the primary driving factor is day length, hours.

00:05:49.060 --> 00:06:06.730
So as long as we have the right number of hours in the right spectrum of light, everything's fine, and we can very easily control or manipulate that to our heart's content we've, talked about that plenty in the past, I think, it's now it's time to really dig down in there and fine tune it.

00:06:07.529 --> 00:06:13.839
Mandelyn, when you start adding supplemental light onto your birds, what do you shoot for?

00:06:13.839 --> 00:06:14.600
How many hours?

00:06:14.860 --> 00:06:16.290
What do you think it takes for your flock?

00:06:17.089 --> 00:06:22.019
In between 14 and 16 hours, going past 16 hours is way too much.

00:06:22.040 --> 00:06:25.709
Dipping under 14 hours, it varies.

00:06:26.060 --> 00:06:44.319
So within that two hour window and when we start really losing daylight, I start backing it up closer to 14 rather than the 16 because I want them to have a natural bedtime and have the lights come on in the morning because that's just another instance of when stress can be caused and you won't get any eggs.

00:06:44.660 --> 00:06:51.740
If those lights are doing an automatic on automatic off with no dim, it'll shock the birds just in that little action.

00:06:52.240 --> 00:06:56.930
They're really more sensitive to a lot of different factors than I think people want to give them credit for.

00:06:57.290 --> 00:06:59.980
Especially plunging them into darkness in the evening.

00:07:00.019 --> 00:07:01.779
That's Yeah, when they're in the middle of eating.

00:07:01.779 --> 00:07:02.420
That's not cool at all.

00:07:02.459 --> 00:07:02.769
Yeah.

00:07:03.240 --> 00:07:05.060
Because their night vision the natural sunset

00:07:05.089 --> 00:07:11.220
is really important, and that kind of signals them to finish up their eating and get on the roost before the sun goes down.

00:07:11.689 --> 00:07:23.129
And if your lights just plunge them into total darkness out in the yard at 545 in the evening, it can cause them to panic, and they could pile, they could stress, they Chickens sometimes aren't so smart.

00:07:23.379 --> 00:07:35.060
They could just like freak out and freeze up out there and need extra motivation, which requires you to put on your snowshoes and galoshes and motivate them back into the coop.

00:07:35.860 --> 00:07:43.639
John, I think you've probably done more research into this than us, other folks here, but what about light spectrum?

00:07:43.649 --> 00:07:44.509
What matters there?

00:07:45.310 --> 00:07:47.550
There's a couple of different spectrums of light.

00:07:47.759 --> 00:07:50.060
that trigger different things in the chicken.

00:07:50.709 --> 00:08:16.240
The easiest thing to remember is if you just get, and it doesn't need to be strong a full spectrum light, and I would actually, so what I've used with great success are very low power it's about, it's a 110 watt equivalent, it's equivalent to the old T5 fluorescent tubes I used to use these bulbs for micro green production, so it's a very, it's like a 5 watt LED strip light.

00:08:16.740 --> 00:08:34.809
But it's full spectrum for greenhouse use, which the plants need, and the chickens just love it, and there is inherently no flicker, and that is more important than anything else, when it comes to lighting, I believe, is that there's no flicker in your light source, cause that will absolutely drive your birds insane.

00:08:35.139 --> 00:08:37.120
It will, make them nuts.

00:08:37.669 --> 00:08:44.279
It's like making them live in a strobe light, to their vision, like you might, you won't see it with your naked eye, chances are.

00:08:44.840 --> 00:08:47.379
But they'll see it as if it's a sterbilite.

00:08:47.519 --> 00:08:47.889
Huh.

00:08:48.210 --> 00:08:53.929
And if you lived your life in a constant rage party, I could see where it could cause some disturbances.

00:08:53.950 --> 00:08:59.649
Our job as poultry keepers is to give our chickens the best life possible.

00:09:00.450 --> 00:09:03.120
Every day of it, and then one bad day at the end.

00:09:03.620 --> 00:09:15.480
So I try to keep everything as chill as possible I keep my lights right now I'm looking for those hens that are just still productive at a 14 hour threshold.

00:09:16.049 --> 00:09:19.580
So when the fall comes, I do dial my lights back to 14 hours.

00:09:19.860 --> 00:09:22.950
So they are popping on at about 3 o'clock in the morning right now.

00:09:23.600 --> 00:09:27.899
But really just 3 of my hens are laying and it's exactly the 3 hens that I want.

00:09:28.340 --> 00:09:32.720
Those are the ones that are going to continue to lay at the lower day length.

00:09:33.519 --> 00:09:37.490
And that's what I'm selecting for and have been selecting for.

00:09:37.990 --> 00:09:48.059
John, you were talking about flicker rate and one easy way to check this, just take your cell phone and shoot a video on slow motion and then play it back.

00:09:48.070 --> 00:09:49.409
You can actually see the flicker.

00:09:50.049 --> 00:09:50.950
And those bulbs,

00:09:51.730 --> 00:09:53.690
And not just your primary lighting source.

00:09:53.759 --> 00:10:00.580
I have a bunch of low voltage Hardy string lights that are all weather and they're outdoors on my porch.

00:10:00.580 --> 00:10:20.750
And I ran some around inside the Garage in the barn just as a kind of low light source And I when I was recording the my lights to see if they were good and they were I Happened to notice in that video that the party lights were strobing and I went oh That's not good.

00:10:20.750 --> 00:10:27.539
And I went over and I flicked them off and it was interesting because it was almost instantaneous soon as I flicked off those lights.

00:10:28.029 --> 00:10:30.720
This is back when I had quail last month.

00:10:31.179 --> 00:10:33.019
They just seem to calm down.

00:10:33.309 --> 00:10:34.399
Quail are wonderful.

00:10:35.049 --> 00:10:36.269
Meters of things.

00:10:36.350 --> 00:10:38.039
They're very, yeah.

00:10:38.149 --> 00:10:39.440
What's the word I'm looking for?

00:10:40.240 --> 00:10:40.779
Sensitive.

00:10:41.139 --> 00:10:41.679
Sensitive.

00:10:41.679 --> 00:10:42.970
They respond very well.

00:10:43.769 --> 00:10:47.580
And you guys saw the video difference between a red light and a blue light in the quail brooder.

00:10:48.159 --> 00:10:48.509
Yes.

00:10:48.820 --> 00:10:49.909
Same thing going on.

00:10:50.169 --> 00:10:52.399
Super sensitive, so now those lights are just out.

00:10:52.570 --> 00:10:54.320
They have no business in my barn anymore.

00:10:55.120 --> 00:10:57.820
It's not a place to, for ambient party mood.

00:10:57.820 --> 00:10:58.840
It's business.

00:10:59.639 --> 00:11:04.399
We talked on it, just a little bit touched on it there, but it doesn't take much light.

00:11:04.889 --> 00:11:05.289
No.

00:11:05.299 --> 00:11:12.299
The recommendation is roughly a 60 watt bulb for every 200 square feet of space you're trying to light your chickens.

00:11:12.840 --> 00:11:14.450
Yeah, that's not a whole bunch of light.

00:11:15.080 --> 00:11:15.539
And.

00:11:16.014 --> 00:11:27.225
The color of the light, that obviously plays a role white lights can be the most stressful, so if you're going to use a white light, I would go for a warm white.

00:11:27.325 --> 00:11:29.585
That's not quite as bad as a bright white.

00:11:29.585 --> 00:11:30.865
Down in the cooler spectrum.

00:11:30.945 --> 00:11:31.215
Yes.

00:11:31.745 --> 00:11:37.034
Red lights it has a very calming effect and it helps prevent feather picking.

00:11:37.835 --> 00:11:49.955
Mostly we see red lights being used in brooders for baby chicks because that's, that has that calming effect and it has that sort of a deterrent to feather picking.

00:11:50.754 --> 00:11:56.855
But, surprisingly, blue light, blue colored light helps promote body development.

00:11:57.044 --> 00:11:57.355
Yes.

00:11:57.365 --> 00:12:12.105
And they have seen Studies where birds have responded when they were chicks raised on blue lights and those birds that were under blue lights were significantly larger than the birds that had been under reds or whites.

00:12:12.524 --> 00:12:22.745
Jeff had told us a story years ago now, and I've seen it in practice a few times and I went, ah, yeah, I remember when Jeff told us about that.

00:12:23.085 --> 00:12:27.625
So around here, a lot of people have clear span structures and they alternate their panels.

00:12:28.090 --> 00:12:29.220
with different colors.

00:12:29.690 --> 00:12:31.980
Cause it doesn't cost any extra when you're ordering it.

00:12:32.070 --> 00:12:35.950
And it's about a 85 percent light transmission cloth.

00:12:36.250 --> 00:12:55.815
But when they're alternating panels of white and blue or white and green, the Chickens will naturally congregate under the blue or green panels and avoid being directly underneath the panels of the filtered light coming through the roofs.

00:12:56.284 --> 00:12:57.677
That's where they want to be.

00:12:57.677 --> 00:12:59.375
Yeah, they choose to be there.

00:13:00.174 --> 00:13:10.434
I can't help but wonder, John and Mandelyn, I want to get your thoughts, but do you suspect that there might be an advantage to using red light and blue lights for birds?

00:13:11.235 --> 00:13:17.004
As long as you're full spectrum, I don't think you need to have a dedicated red light and a dedicated blue light.

00:13:17.504 --> 00:13:22.125
It sounds like you could almost put them on separate ends and figure out which ones the birds like better.

00:13:22.195 --> 00:13:22.784
Good point.

00:13:23.585 --> 00:13:23.664
I

00:13:23.664 --> 00:13:24.965
mean, for science, for sure.

00:13:24.985 --> 00:13:27.024
I just want to say that'd be a good little experiment.

00:13:27.164 --> 00:13:32.034
Put food and water on both sides under both colors and see what their preference is.

00:13:32.565 --> 00:13:48.529
Or if we really want to get fancy, in the horticultural world, there's something called an Emerson effect that we chase, which is a gradual phasing in the morning from blue into the yellow spectrum, and then into the white, and then in the evening gradually phasing into the ultra white spectrum.

00:13:49.129 --> 00:13:50.720
Or the deeper red spectrums.

00:13:50.860 --> 00:13:55.470
Would that have anything to do with mimicking what the sun does naturally?

00:13:55.519 --> 00:13:58.080
That's precisely what we're doing in the horticultural world.

00:13:58.080 --> 00:13:59.269
Yeah, it's called the Emerson effect.

00:13:59.279 --> 00:14:02.610
And a lot of plants actually trigger off of that.

00:14:02.889 --> 00:14:06.690
Because there's things like the Krebs cycle there's photosynthetic plants.

00:14:06.860 --> 00:14:11.080
Dependent cycles and there's non photosynthetic dependent cycles, but we're getting off track.

00:14:11.080 --> 00:14:13.440
Do

00:14:14.240 --> 00:14:16.429
you know why they call it the Emerson effect?

00:14:16.929 --> 00:14:21.490
When they're raising baby chicks, they go through and they say, Emerson, nice chicks.

00:14:22.289 --> 00:14:23.000
Sorry, folks.

00:14:23.000 --> 00:14:23.389
It's beautiful.

00:14:24.164 --> 00:14:26.315
And

00:14:26.394 --> 00:14:29.815
with me being up here in Ohio, that's why I've not heard that.

00:14:30.615 --> 00:14:30.705
I

00:14:30.705 --> 00:14:34.164
have to go see my family in Tennessee before I hear stuff like that.

00:14:34.965 --> 00:14:35.625
You're deprived.

00:14:36.424 --> 00:14:37.024
What about.

00:14:37.825 --> 00:14:49.485
The number of eggs a hen will lay, a lot of folks don't realize that pullets are born with all the microscopic eggs that they will lay in their lifetime.

00:14:50.284 --> 00:14:50.684
What about

00:14:51.054 --> 00:14:53.955
So do chickens on the equator run out of eggs?

00:14:54.475 --> 00:14:57.325
Before chickens appear on the 45th parallel, because

00:14:58.044 --> 00:14:58.654
I don't know.

00:14:59.054 --> 00:14:59.274
Good.

00:14:59.274 --> 00:14:59.914
Very well be.

00:15:00.715 --> 00:15:04.485
Or are they more seasonal layers like junglefowl are?

00:15:05.284 --> 00:15:18.975
Cause if they're a seasonal layer and they're really active for six months or less out of a year, those are the birds that are going to lay much longer into their life versus highly productive bred birds.

00:15:18.975 --> 00:15:22.644
Like when you look up a leghorn, what is it annually for that first year?

00:15:23.445 --> 00:15:24.504
53,

00:15:25.304 --> 00:15:26.924
320 to 350.

00:15:27.445 --> 00:15:33.184
That's almost an egg a day for an entire full four season year.

00:15:33.985 --> 00:15:39.264
And that's definitely productive and not just a seasonal layer.

00:15:39.595 --> 00:15:43.745
Like I know from my heritage turkeys, they're going to be a seasonal layer.

00:15:43.745 --> 00:15:49.115
And at most I'm looking for 90 eggs out of a whole calendar year because they're going to do it seasonally.

00:15:49.705 --> 00:15:58.355
All the other chicken types, they're going to fall within that either being productive bred or being a little more seasonal based with some flex.

00:15:58.695 --> 00:16:03.904
Like an average dual purpose kind of bird, they might only do 175, 220.

00:16:04.085 --> 00:16:08.365
They're not probably going to push it fast past 250 eggs a year.

00:16:09.134 --> 00:16:14.554
And how they're grown even will impact how many eggs you could expect from them.

00:16:15.184 --> 00:16:25.475
And when they do have those layer at egg output numbers, it's going to be more based in the spring and you might be hard pressed to get eggs from them in October.

00:16:26.274 --> 00:16:37.684
And that's how it's easier for me to collect from those, the hens that I want to breed from, they're, they were my five to six egg a week hens, and now they've dropped back to three or four a week, but they're the only ones still laying.

00:16:38.485 --> 00:16:42.815
Yeah, that's definitely what you want to hatch from if you want to have that year round kind of production.

00:16:43.054 --> 00:16:50.274
Yeah, and if we're looking at it's November 22nd, I need chicks available, point of lay pullets at 18 weeks on the 1st of April.

00:16:50.975 --> 00:16:53.595
Time to start thinking about these things and getting that nutrition.

00:16:54.394 --> 00:17:02.355
One thing I wanted to talk about here, and this is a good spot to bring it up, is early laying, early sexual maturity.

00:17:03.154 --> 00:17:10.605
I know a lot of folks try to push as much early sexual maturity as they possibly can out of their birds.

00:17:11.065 --> 00:17:13.115
I deliberately try to delay it.

00:17:13.595 --> 00:17:14.015
Yes.

00:17:14.414 --> 00:17:23.884
The nice thing about winter hatching is if I could get them on the ground, On a regulated light cycle, then I can put them on a natural light transition.

00:17:23.894 --> 00:17:30.585
So just as they're coming into their production age, the natural light cycle is triggering that for light stimulation.

00:17:31.285 --> 00:17:39.154
And I'm perfectly fine keeping them in the dark for a week or two longer for better maturation, better carcass and frame development.

00:17:39.355 --> 00:17:39.724
Yes.

00:17:40.444 --> 00:17:46.424
I've got big hands, so processing birds, I need those pin bones as widely spaced as possible.

00:17:46.424 --> 00:17:48.694
I'm starting to think selfishly now.

00:17:49.005 --> 00:17:53.125
But for my own ease and use, that's becoming more and more important.

00:17:53.125 --> 00:17:55.134
And of course, it's beneficial for the hens.

00:17:55.134 --> 00:17:58.704
Mandy is always talking about that pin bone spacing for production.

00:17:58.744 --> 00:18:04.734
You only have to have those bones dig into your wrist a couple of times before you start figuring out why and how to fix it.

00:18:05.059 --> 00:18:09.579
Now I can get my hands so far up into a cockerel, I can scoop the lungs by hand.

00:18:09.910 --> 00:18:13.069
Yeah, and those nitrile gloves are expensive.

00:18:13.069 --> 00:18:17.079
I calculated them out, they're four and a half cents a piece, even when I buy them by the case.

00:18:17.660 --> 00:18:19.490
And you don't want to go through a pair of bird.

00:18:20.289 --> 00:18:20.569
Nope.

00:18:21.369 --> 00:18:38.940
Part of the problem with this early sexual maturity, early laying, Is that once a pullet starts laying, she's pretty much going to stop growing because she's channeling all those nutrients and energy into producing eggs and not to producing body mass.

00:18:39.490 --> 00:18:48.380
You also only get smaller egg size from those early maturing females, and it will take them longer to get up to a hatchable size.

00:18:49.089 --> 00:18:52.710
And sometimes they don't, I just started saying sometimes they don't do that.

00:18:53.509 --> 00:18:58.069
You have an increased danger of prolapse in those early laying birds.

00:18:58.549 --> 00:19:09.650
That's where the egg gets hung up in the cloaca and the birds keep pushing and pushing trying to get the egg out and they actually have part of the cloaca hanging outside of their body.

00:19:09.910 --> 00:19:11.970
And once that happens it's never a good thing.

00:19:11.970 --> 00:19:15.210
Sometimes you can treat it, but sometimes it just doesn't work.

00:19:16.009 --> 00:19:23.650
And those early laying birds, they found that Lifetime egg production can be reduced with commercial flocks.

00:19:23.650 --> 00:19:31.069
They don't worry about it because they bring birds in, they let them lay for a year, and then they're out the door to the processing plant and they bring another bunch of birds in.

00:19:31.869 --> 00:19:34.599
But for us, longevity is important.

00:19:34.970 --> 00:19:36.859
Long laying times are important.

00:19:37.660 --> 00:19:44.910
Something to think about it's, and I get really frustrated on some groups because it's like they seem to have a competition.

00:19:44.910 --> 00:19:46.569
My bird started laying at five months.

00:19:46.789 --> 00:19:50.019
Oh mine started laying at four months and I'm sitting there pulling what little hair I've got.

00:19:50.029 --> 00:19:51.329
Ooh, I got my first egg at

00:19:51.329 --> 00:19:52.190
12 weeks.

00:19:52.240 --> 00:19:53.990
I'm like, Oh no, that's not good.

00:19:54.789 --> 00:19:56.289
That's not something to brag about.

00:19:56.569 --> 00:19:56.950
Okay.

00:19:56.950 --> 00:19:58.779
I'm going to get down off my high horse now.

00:19:59.569 --> 00:20:00.309
Oh, heck no.

00:20:00.309 --> 00:20:00.789
Enough said.

00:20:00.869 --> 00:20:02.720
This is so important because you're.

00:20:02.884 --> 00:20:07.285
Literally selecting and breeding for in the wrong direction.

00:20:07.785 --> 00:20:16.394
And with what we know about epigenetic development, you keep doing this for a generation or two, and you are severely locking yourself in.

00:20:17.194 --> 00:20:19.424
And you might as well start raising bantams eventually.

00:20:20.224 --> 00:20:23.029
Because my breed can be prone to that early.

00:20:23.319 --> 00:20:27.920
maturing, if they start laying before 18 weeks, I already know they're a cull.

00:20:28.279 --> 00:20:30.930
I already know I don't need that bird anywhere near a breeding pen.

00:20:31.180 --> 00:20:33.720
18 weeks is the absolute soonest.

00:20:33.730 --> 00:20:42.200
And it depends on her weight and her bone spacing on if she gets to continue doing that or not, because if they get started early, okay.

00:20:42.440 --> 00:20:44.519
but do they check out on everything else?

00:20:45.309 --> 00:21:01.730
Because depending on their development, it might be early for what they're built for, and some of them did need another month to grow and finish up, so it's a lot to look at if they get started before 24 weeks.

00:21:01.730 --> 00:21:03.980
You need to make sure everything else checks out with them.

00:21:04.380 --> 00:21:04.700
Mandelyn,

00:21:05.500 --> 00:21:11.410
what about selecting breeds for Your egg laying goals for your flock.

00:21:12.210 --> 00:21:13.220
What's your thoughts on that?

00:21:14.019 --> 00:21:16.359
It really depends on what you're trying to do with them.

00:21:16.359 --> 00:21:24.069
And if you're trying to have a little side hustle for selling breakfast eggs, then you're going to want to have predictable production.

00:21:24.569 --> 00:21:33.470
And that means you're going to want those leghorns and other high producing birds, or even sex links that have that built in.

00:21:34.269 --> 00:21:38.289
Gender identification at hatch and the higher production levels.

00:21:38.509 --> 00:21:49.500
If you need it to be a business model, then you want to skip the slower producing birds because you won't be able to predict your eggs.

00:21:50.164 --> 00:22:01.115
Now, if you want just your own basket and you're okay, whether you get three or 10 eggs a day, then you can start looking at other attributes in the breeds that you want to have.

00:22:01.914 --> 00:22:07.125
But you have to make that choice between production and I'm not that worried about it.

00:22:07.924 --> 00:22:09.184
I lost my train of thought here.

00:22:09.335 --> 00:22:10.025
Imagine that.

00:22:10.805 --> 00:22:12.924
What about dual purpose breeds?

00:22:13.724 --> 00:22:18.174
Give us your honest evaluation on dual purpose breeds as egg layers.

00:22:18.974 --> 00:22:22.325
I got my thoughts, but I want to know what y'all's are.

00:22:22.325 --> 00:22:22.575
They better

00:22:22.575 --> 00:22:23.125
perform.

00:22:23.634 --> 00:22:24.365
Otherwise they're out of here.

00:22:24.365 --> 00:22:24.595
They

00:22:24.845 --> 00:22:25.835
have to perform.

00:22:25.835 --> 00:22:26.204
Yeah.

00:22:26.255 --> 00:22:29.565
I think it's easier to squeeze an egg out rather than a meaty carcass.

00:22:29.934 --> 00:22:49.494
The meaty carcass seems to be more elusive and trickier to get in there because of how much breeding work was done towards those eggs, especially over the last 60, 70 years, everything's more reliable at laying than doing the meat part.

00:22:49.664 --> 00:22:52.525
So I preserve the rate of lay.

00:22:53.325 --> 00:22:53.875
They don't, they.

00:22:54.285 --> 00:23:03.424
What I'm fooling with didn't need much work on the egg laying part, so I was able to focus more on the meat and just making sure the eggs stayed exactly how they were coming.

00:23:04.224 --> 00:23:08.634
How many, on average, how many eggs do you get from a female, Mandelyn?

00:23:09.434 --> 00:23:12.775
I need them to do a minimum of five a week, but six is better.

00:23:13.575 --> 00:23:14.505
John, what about you?

00:23:14.575 --> 00:23:15.535
What are you shooting for?

00:23:15.924 --> 00:23:16.285
Five a

00:23:16.285 --> 00:23:17.755
week, six would be better.

00:23:18.085 --> 00:23:22.154
Last year I had a hen, she laid non stop.

00:23:22.424 --> 00:23:23.275
Never took a pause.

00:23:23.775 --> 00:23:26.424
So I set every one of her eggs I could get.

00:23:26.724 --> 00:23:31.015
She was also my rogue hen, so I set every one of her eggs I could find.

00:23:31.815 --> 00:23:32.615
Makes a difference.

00:23:33.015 --> 00:23:45.954
And I've had a couple of dual purpose breeds before Brahma's come to mind, where I didn't get a first egg until they were eight, nine months old, and after they were in active lay, it was only three eggs a week.

00:23:46.755 --> 00:23:51.785
And then once they saw a grouping of three eggs, boom, now they're broody.

00:23:52.585 --> 00:23:56.015
