The first time it happened was a couple of weeks ago when i ealked out to find one of my hens up against the fence eith its head pulled off. Then two days ago i went out to feed and onr of my ducks had its head and neck almost pulled off but not quite. Then yesterday morning i walk into my coop and theres 5 dead chickens, 4 which had their heads pulled off, a dead duck which almost looked normal save for a small bloody spot on the back of its neck, and 10 missing pullets. I found most of the pullets bodies behund the coop in the farmers field and the tall weeds all except one with their heads pulled off. The only place something could have got in was a 2 or 3 inch gap under the door, and when i walked up to my chicken coop when of the hens was halfway pulled underneath the door,
