We think that my drake is drowning other birds and plucking all if their feathers. This has happened to a chicken and a female duck. The last time it happened we caught him in the act he was torturing the female duck after pulling all of her feathers out and was trying to drown her. Why is he doing this? Can i stop him from attacking my other birds? For the record he has never been aggressive with anything before he has grown up with the chickens and the other ducks. The killings were about a little over a week apart.
