About a month ago I integrated 2 flocks for a total of 10 pullets - 1 cockerel. The older pullets should be laying within a couple weeks and are dominate. The 'new' pullets and cockerel are unknown age but pullets appear about 3 months old. Cockerel started crowing 2 weeks ago, I'm guessing he is @ 4 months old. There was the normal pecking and chasing but it was never violent and has mostly settled down. The cockerel has hung with the young girls he came with and tries to breed them (a lot ) The last 3 nights he has started pecking the young girls as they come to the roost. He bullies them so bad they holler and fall/jump down. He will eventually allow them to stay on roost if they turn backs to him and hunker down but it is stressing them (and me) out. I have 2 roost boards, each 6 foot long, 8 inches apart so there is plenty of room. I snatched him off the roost last night and put him in chicken jail until late morning. I made sure all the girls saw me holding him and then put him in cage they could see. I worked in coop around him all morning so he would be near me and hopefully see me as dominate but kind. I should mention all the newer birds are not tame. The cockerel is a Light Brown Leghorn so he is especially flighty. They will now come within 6 feet of me, before it was twice that, but still run if I walk even near them. My older pullets are very tame, they sit on my lap or chair and follow me around the yard. He does not bully the older pullets, they kick his butt daily. He isn't even big enough to think about eating. *Sigh* I had such hopes for him, he is beautiful and I really wanted a protector for the girls. Is there any hope he will overcome these teenage hormones? He is so young I'd like to cut him some slack but this seems a pretty serious flaw. Perhaps once the older pullets begin letting him breed he will move to that flock? Has anyone else experienced this with a young jerk of a cockerel?
