Hi, I am a new duck owner, I have a natural pond in my yard so I recently got a couple of call ducks from a farm, they are a mated pair. The day we brought the ducks home a pair of wild calls decided to make our pond home too. Our ducks are in a pen next to the pond and we have been letting them out once a day to swim under our supervision, the wild drake is very aggresive with my drake. He chases him out of the pond as soon as I step away, he seems to be going after my hen even though he has a mate. My drake is fighting back and they are very rough with each other. What should I do? I cant pen the wild ducks... Will the drakes sort things out eventually, what is going on here? Thanks!
