I’m all for trying to rehabilitate a bird if appropriate. But, from all your posts here what I think I’m hearing is apprehension and hesitancy from you.He’s been great! I know they mature slow, but he is so good with the girls.
We could probably put a divider back up and keep the cockerels on one side and all the girls on the other.
I could also just let him out with the hens and see if that helps. I’m willing to try if we think there is a chance it’s just his hormones making him act like this. It was just so sad seeing Leslie limp. The other one ran right to me too, and they are not “lap” chickens like the lavenders. They would prefer we keep our distance so I know they are stressed. They barely have full crops at night. I have to feed them separate.
I think the easy answer is the right one. Let the EE go to a new home with a mature flock who can teach him manners.
Let the brahama, who you said has been great thus far, give it a shot. And hope he keeps acting right.
Edit - If you start having trouble with the brahama, at least it’s only one bird you have to worry about segregating. I also think chicken timeout is more effective if he doesn’t have a buddy with him.
