It lasts them until about 5-6pm. I will usually see a small amount left in the pan when I go out to check on everyone at sundown, but it's gone by the time I check in the morning.
I am leaning more towards this because I am not seeing wounds or irritation. They're just naked/thin-feathered looking. Almost like the fluff is disappearing but the adult feathers haven't caught up.
Yes! These chicks are HUGE for their age!
I'm actually kind of intrigued because I wasn't planning on keeping them after I saw their attitude. And they require WAY more feed than I'm used to feeding, which is another mark against them. That's money, after all.
But I have a black copper marans rooster that throws monster cockerels. I have put him over other marans and barred rocks. They hit 6-7 pounds by 10 weeks, they make my full grown adult cocks look ridiculous, and they achieve this without eating more than my regular layers.
So now I'm thinkin'.

I wonder if I could keep the two pullets in this group and breed them with that roo, and see if I can "fix" their crappy food conversion rate while keeping that double breast, and they should (in theory) be sex-linked chicks. I might have me a cool project for 2023-2024.
