This morning I came out to the coop to find their food knocked over and a clear disturbance. There were a few small chunks of feathers and my 8 week old cuckoo bluebars are gone. No blood. I cannot find a point where a predator would be able to get in and then also remove two birds without a huge mess. Any ideas what it could be? My only thought is that the auto door may have not closed last night. I'm so sad.
