My ducks do this to when there being snotty. I get my friend Nicole to come over and we grab a really long rope and drap it across the pond while kinda making it like a jumping rope. The ducks get scared and run out. Keep them locked up for a couple days then let them out keep doing the rope thing until they Lear than when you show up get out or else. This is how I can now heard my ducks down the raid like a parade and they will listen. It's kinda like training a dog. Plus if there good and get out of the pond they get some chopped up apples and beets.
