I have a roo that I think is plucking the feathers off 2 of my hens. The last time I went down there all the feathers wsa gone off of her neck and her comb was gone. The other one her feathers and all was off of her back. The one with the comb gone is the one that lays on all the eggs and she did have 5 chicks this year. The 2nd time the babies didn't make it. What is up with him? Can I kill him yet?
