We think it was a fox. I forgot to lock the chicken coop up, fell asleep in the recliner chair, woke to chickens cackling. So other than get a few dogs (in the process I hope) any suggestions on automatic door closers, sesnory lights and music on automatic timers? Any other suggestions would be helpful as we just lost our hound dog who sort of watched over the flock. They are freerange chickens with a tight coop, when the door is closed. Thanks. Anita
