Sometime during the middle of the day yesterday something entered the run of our coop and broke the necks of 14 of our chickens, leaving them laying in the run and coop. One was found just outside the run and another was found about a 1/4 mile into the woods behind our house. I'm missing about 5. There is one entry spot in the run and 3 exit areas where they forced their way out. All of the chickens left behind have two puncture wounds where it looks like something grabbed it with it's mouth and shook it. We are thinking a pack of coyotes but are surprised that this happened in the middle of the day. Anyone have any thoughts?
