My 1 year old chinese gander is getting really, really aggressive. He bites the chickens, rips feathers out of their backs... and whenever I go out, he starts to bite me. I grab his head, yell at him, and sometimes squish him on the ground, to establish dominance, but the second I let him up, he's trying to bite me again. I love the goose, and don't want to give him away. He hangs with a pack of ducks, DH says no more geese, so a wife isn't an option.... are there any tricks? any advice?
