Holy cow! This must be why weasels have such a bad reputation for just being devious and mean. Why in the world would they attack the chickens and not eat them? That's horrible! So sorry!!!I think it was a weasel. They are vicious little things, and go after anything that moves, and won’t stop until everyone is dead. A weasel got 2 of my feather babies a while back. They looked perfectly fine except for a little blood on their heads and faces. The next night it returned and got our little bantam polish. Body was untouched on the ground, but without a head. We found the head in the chicken feeder.
