Yesterday we found a headless hen in her nesting box. We could not find any evidence of her head in the coop, in the enclosed run or around the outside door of the nesting boxes. There were no feathers or blood or any other signs of a struggle. We didn't find any holes through or under the fence that surrounds the run. It is possible for something to have jumped the fence and gone into the coop through the little chicken door, but why go through all that work for just the head? The nesting boxes are accessible from outside of the run but one would have to lift a the heavy lid and hold it to get to a hen. I originally though that maybe one of our kids caught her head with the lid when they gathered eggs but there is no way it would have cut the head clean off and my kids would have been traumatized. We have all the usual suspects...wolves, fox, bobcat, dog, skunk , opposum, hawk, owl etc, thoughts?
