Ok.... in the last week something got into our run and completely gutted a chicken. Just the skeleton was left.... then the next day (could be unrelated) something killed a wild bird and her babies from a nest off a bush near our driveway. Then last night something killed one duck and ate it’s neck.... then I come out this morning to find bits and pieces of our male duck all around the run and a massive hole dug by the fence. We’ve done a ton of predator proofing, all but burying wire around the run due to its size. Any ideas on what it could be?
