I built a coop this summer and lock my birds up every night. The coop is 100% secure. It has been called a "Duck Fortress" by one of the breeders I get ducklings from. Well about 10 days ago my Muscovy duck decided she no longer wanted to go in the coop at night. Instead she flys up to perch on the run above the coop. I have a friend who runs a duck rescue and she said that she should be fine since she is perching on top of the run and she flys very well. Well this morning my wife went out to do chores and open the coop and Ms. Sassy Feathers was dead on the ground in front of the feed bowl. She had a huge wound on her neck that essentially decapitated her. There was no other injury and it doesn't look like she was eaten at all. I went out last night around 10 to let the dogs out before bed and she was perched in her usual spot. I heard a barred owl but it was quite a way off in the distance. We do have a healthy population of those owls around here. I am guessing it was an owl? Does anyone have other ideas based on the injury? Since she was in front of the feed bowl I'm guessing she flew down to eat and got attacked from above/behind and didn't even see it coming. I am very sad and a bit concerned now since I don't know which predator it was. I just feel awful and kick myself for not trimming her feathers and forcing her to get in the coop at night. I wont make that mistake ever again.
