Hello everyone! I really hope you can help me with this problem. I have a Black Australorp, who is an absolute gem to people, but evil to the hens. He is young, and I am aware that some go through a phase, but he is aggressive. After mating, (quite brutally) he will continue pecking the head and comb of the hens. My 8 week old chicks are small enough to escape, and when they got to where he was, my rooster picked one of them up by the scruff of the neck and shook her/him. He has left my speckled sussex with a gaping hole in the back of her head. He chases the girls around and doesn't give them a break. Is there any way to stop this behavior?
