So I have seven ducks. Four duckling, a drake and two female ducks. The drake and one duck walk around together, while the ducklings and there mother walk around together. Sometimes, for no reason, the drake will run to the ducklings and chase them and try to peck them. He even picked one up once! He just chased the mother of the ducklings today, but he never chases the other duck. Is there a problem, or are they okay?
