This is a new one for us...this morning about 9:00AM I heard our chickens in the barn raising cain and rioting; going on and on, for about a half an hour. They had already had breakfast and the barn doors were open for the day so they are free to come and go. Many prefer to stay in or near the barn, rather than free range. It is not uncommon for them to raise a riot for whatever reason, so I didn't pay any attention. Went to the barn at noon and found a hen lying on her back under a shelf in the barn; something had eaten all her innards and head; I mean it looked like she'd been cleaned ready to be packed for the grocery, because the rest of the meat was untouched, and she was entirely intact. Anyone have an idea what would do this? We've had raccoons, possums, and skunks; in the past they have always eaten all, or most of, the whole bird, and scattered the rest! I know that dogs will not usually touch a bird after they kill it; and we have not seen any strays. Would a fox do this? And during the day?
