Help my hen is getting beat up by my rooster. He wants to kill her she has some blood on her head he just keep attacking her. I put her and two other hens in with him and he is fine with the other two but her he keeps chasing her. So I took her out of there put her in another one of my pens and they are doing the same thing but only the hens ganging up on her. So I put her in a pen with a hen and chicks of course you know what happened so now she is by herself in a rabbit.hutch. What to do now?
