I had an incredibly aggressiveale duck that would come after me all the time. He was big, like 20lbs at least, and I’d kick him in the chest with the side ofy foot when he came at me all angry like. His chest was the meatiest part of him, so I wasn’t worried about damaging him with kinda wimpy kicks. Bastard became soup real quickly, though. Overly aggressive birds in my flock don’t get the privilege of being pets.
