I have two banty brahmas-one light, I think it's a hen, one buff, I think it's a roo. Neither one is terribly friendly with the other birds. In fact, I have seen them both pick on the others. When I pick up the buff he turns around and pecks at me. I have never had a chicken peck at me like he does . Usually they squalk but never nip. Is this typical of brahma behavior?
