I have never struck her, I believe that hitting only makes things worse. They don't understand spankings. I have pinned her, I have chased her with my arms spread hollering at her when she went after my mom. I have even tried hissing at her when she came for me from behind while I was enjoying some attention from my Chinese geese. That time Snow, Jasmine, and a couple other geese went after her for me! I would swear they were just as upset over her behavior as I was. She often tries to bite and bully the other geese, and she has gone after the ducks and chickens. She just may not be compatible with our flock. She was raised with all these guys, but attacks anyway, even her own kind. I am thinking it may have something to do with badly bred hatchery stock. She needed months of TLC to get her legs strong, and now she is just plain viscous and refuses to learn or back down.
