Left for two hours, chickens free ranging, hubby home. Get back, one is missing, Spot, a very small 'mutt' - hubby has not heard a thing, no panicky chicken sounds, no dogs barking or fighting, or anything...check about, no blood no feathers! But...find one leg, a gizzard and part of a gut. That's it. Dogs are clueless, no blood on them either, other chickens are ok, not freaked out. So...would a raptor leave bits and pieces? Another clue, bit and pieces were found under a large tree. I'm thinkin....raptor gets chicken, flys to branch, proceeds to kill and pick apart a bit, then flies off. Does this sound characteristic of a hawk, eagle, owl attack?
