At about 4 weeks we were able to tell the majority of the chicks apart by their combs. The Males developed color on theirs first. I have seen fighting among the males. Nothing bad though. No one ever gets hurt.
Someone always runs away.
They are very quiet. Right now most of them are free ranging and doing a good job of it. It'll be time to put most of the males in the freezer this month. We have about 51 females for egg laying and setting. This is a private posting area.
