Good morning, We've had two Blue Swedish ducks for a little over a year now, and Bought two more Pekin about 12 weeks ago. We have the Pekin outside now, since they are full grown (bigger than the older ducks now) but have them separated, although they can still see each other. They've been living this way for a few weeks now. I've let them mingle together once, and lets just say it did not go well. My older male duck started to violently chase them, and pull their feathers out. Is there a better way to go about letting them live together? Also, My one Female Pekin hasn't started to lay eggs yet, do I need to wait on letting them live together until she does, since she is still eating different food than my older Blue Swedish female?
