I'm confused too. In your OP it sounds like this is a seriously aggressive bird that flails or flogs people who turn their back to him, and he has drawn blood. Victims of his aggression include you, your mother and grandmother as well as the dog. You want help dealing with it. And then in a later post you say it's not a problem any more. Why not? Do you keep him locked up so he can't get close to people any more? What's changed?
