We have 2 American Buff geese and 4 ducks all hatched on May 1 and being raised together. About a week ago the female gosling started biting the male gosling and pulling feathers. He doesn't fight back. When the ducks have bit at him he doesn't stand for it and bites back. The female's attacks got so bad that 3 days ago we put her in a dog cage to keep her apart as she was going after the ducks too. The male sits by the side of the cage for most of the time. Today she was let out and within 5 minutes the attacks resumed. Can she be broken of this habit?
