I have slowly started introducing the new ducks. at first I let the new guys quarantine then showed them to each other so they could see them but not be with them. next I let them outside together and my less dominant duck kept going back and forth with the the new guys and his friend. After about a week of that i am trying to let them meet each other in a confined space to try and see if they could eventually be cooped up with each other and so far my dominant duck keeps starting fights with the newbies. Should I let this happen or should I keep separating them?
