I have had 3 ducks for going on 2 years now. 1 call duck and 2 muscovy. They had a coop in the backyard that they would stay in until winter. This morning they were all outside of the coop within 15 feet of each other all dead. The muscovy were both missing their heads and necks but the call duck was completely intact. No blood, no mess of feathers. The coop door was tilted inward at the bottom and the top hinge completely bent. What could have done this? I live in northern Illinois, in town. I thought maybe raccoons but I don't think the raccoon could have bent the metal hinge into almost 45 degree angle. I couldn't even do that. So I'm wondering, what could have done this, an animal or an angry neighbor?
