Well our rooster Oliver is ripping up the hens backs. He shares a flock of 15 hens with 2 other bantam roo's. However he is top dog. He already scares me enough and now he hurting the poor hens...pecking there feathers right in half, and even completely off. The other day we separated them putting the worst hens in the stall with the red cochin rooster Rocky. Please give me advice on how to help our poor girls.
