Well she's beautiful, and I understand completely. My ducks are pets and I don't have the heart to get rid of my Tuppins. I'm willing to put in the work to monitor them, even though I complain about it. I'm not sure what's driving the behavior for your ducks since they're a little young for mating behavior (I'm not an expert on that), but that seems to be a part of what I'm dealing with, so I wonder if once your babies get a little bigger and join the other ducks, whether things might settle down, since they have a drake and new "pecking order" so to speak. Let this one heal up fully and then slowly introduce them to your older ducks and watch them a lot. Since you just have these two babies though right now, make sure you have them separated by a wire fence, or something they can see through or they will be too lonely. My ducks lay right next to the fence, so they can still be together in their little group!
