Well just removed 6 boys (5 immature cockerels and one rooster) from the main coop and switched them out with the 6 new girls. I left the more relaxed mature cockerel in there. He's 7 months old now and needs to learn to be a man and quit getting beat up by the girls when he tries to mate with them. He doesn't pick on anyone, so he got to stay. All the girls are freaked out about the change and no one is picking on anyone. So it's good out there.
