today when I got home form work I went to check on my chickens and one was lying dead in the middle of the coop with just its head and neck gone. The rest of the body was there. This chicken was in its brooding stage so it was sitting on the eggs. But when I went to get the eggs they were gone so I am thinking that something wanted the eggs but she was sitting on them, so it killed her and took the eggs. My question is what would do this in the middle of the day and only take the head of the chicken.
