I have a very nice docile OEG bantam roo that is trying to kill an ISA brown hen. I put her in the barn away from all the others to heal & I just finally put her back outside today (after a couple of weeks) since she was all healed. He found her already & has pecked her eyes so bad she can't open them again & she is all bloody. Is there something wrong with her? Can they tell that maybe something isn't right about her & she needs to be put down? I am just trying to understand why he would do this? He is a very nice roo. Any ideas? Should I just put her down myself? Thanks!
