I posted about him before. He's about six months old, I raised him from the day he hatched. I got him some lady duck friends last week. He's still pretty mean, and will chase me and nip. I can't go into his cage to change food and water without him attacking my hands. I'm worried for other people. He generally only chases me, but I don't want him to start being mean to others. My neighbors have to watch my flock next month. How can I try to make him more nice? When he bites I just pick him up and hold him.
