Stuart is a Barred Rock rooster with 3 Barred Rock hens. Two of which have no feathers left on their backs, parts of their wing areas and I noticed bare spots on ones neck. Yesterday he grabbed the head hen by the neck and made her yell. Their backs have small scabs on them now. Does this guy need more hens or is he being a bully? I'll be happy to get him 3 more. When I had just hens life was so much easier.
