So I have 2 probable extra roosters in my approx 3 month old black bantam cochin lot and white topped polish lot (one of them is all black tho). I also have a lone game type bantam hen probably over a year old in a small coop perfect for two that was given to me a month or so ago and was in with roosters before I got her. She is black with a reddish head. Id like to give her a mate. She is laying daily. How old should the rooster be before I put him in with her? Should I worry they will fight? Would you pick the polish or the cochin as a cross? We use the chickens for eggs and the extra roos we get will likely end up meat if that matters on the cross. We are brand new with chickens so I have never introduced any before. I dont want them to get hurt.
