I have a ButterCup Roo who is pretty friendly towards us, but he has picked all of the feathers out of my Austrolop neck so bad that she is bleeding. Even when they are free ranging he chases her and picks her neck feathers. He does not even try to mate her he just wants to bloody her neck. I am afraid if not her, he will do this to another hen. I am really having to doctor her neck, it doesn't look good. He is the king of 18 hens so he has plenty of girls and he is definitely mating them so I don't understand. His favorite, EE, has a few back feathers missing but that is understandable, this neck thing is on the verge of cannibalism if you ask me.
