I have 3 buff orpingtons - 1 rooster and 2 hens. They are all about 9 months old. As soon as the rooster started showing male traits and signs of aggression, we starting establishing our dominance back - carrying him, not letting him get away with attacking our feet, etc. All in all, I've really enjoyed having a rooster even if it wasn't expected when I got chicks last spring. He does a great job of protecting the hens from predators when they are free ranging. I hardly have to keep an eye on them when they're out. And it is quite charming when he finds bugs or treats and calls the hens over. The problem started in early December when one hen went broody. He was attacking her. At first, I thought it was because she didn't want to breed because of the broodiness, so I separated them for a while. She is over the broodiness now and laying again, but has a complete different disposition about her - scared and submissive. She was the top hen before this all started. Now he attacks her all the time, but not in a way were he is chasing her and trying to breed. He goes straight for her head/neck. When they are out when I'm home on the weekends, she hides behind me when the rooster is around. I leave them in their coop/run when I'm at work and I'm pretty sure she hides from the rooster behind the crates I use for nesting boxes all day. They do all roost together at night though. He is also a bit more aggressive towards me in the last week or so as well. I can handle him, I just worry about him killing the hen or pecking her eyes out or something. I have heard that more hens to keep him busy will help. I'm planning on getting 8-10 chicks this spring, but I'm not sure this dynamic between the hen and rooster can last that long. Is there anything I can do to change the rooster's behavior toward this hen? Otherwise, he will have to find another home or become dinner. It is hard because they are all my babies.
