One of my golden laced wyandottes was being very aggressive today. She is definitely the gal that's in charge, but this seemed to be more than just a warning peck. She sort of grabbed one of the BA's by the neck. A little later I was nearby, cleaning the coop, when I heard a bit of a ruckus. I turned around to find her standing, literally, on top of one of my barred rocks. Her feet were planted right in the middle of her back. This hen looks exactly like my other female GLW and nothing like my friend's GLW roo, so I don't think it was a case of trying to mount for mating. This particular hen also tries to peck at my son when they are on the roost and he is petting any of the hens near her. The other day she grabbed a hold of his sweatshirt. (More than a peck.) is this behavior out of the norm, or nothing to be concerned about? I don't want any of my girls getting injured by a bully!
