Our 2nd hen was killed (same as the first), not eaten, not taken away, left in same position. Back end has bite marks, feathers all over but this time predator left his markings in the coop (about the size poop of a 20 pound dog). We are all fenced but we forgot to close the hatch to the run last night!!!! We haven't seen stray dogs. What other animal could this be? So sad!
