We got 10 ducklings this spring (early march), 6 Pekin & 4 Kacki. We grew them out for about a month in a brooder then another month in a field shelter, once I opened the field shelter door they never would go back in it, I had built it as a house for them, but they had other plans I guess. We lost two kacki first found them both floating half eaten today we notices a Pekin missing, all we found from the one today was a couple feathers and a small chunk of flesh. The Kacki were smaller maybe 3 lbs or so this Pekin was pretty much full grown though (probably 8-10 lbs ?). I have put bait lines out figuring it was a snapping turtle, some have been cleaned off but it could be minnows to though. No luck catching anything. Any other ideas on predators, how to get rid of them ? Pond is about an acre or so
