At the risk of being morbid...I couldn't tell from the pics, but were their heads mangled up? This spring we had a weasel get into our coop and kill half of our hens. Weasel's usually kill by grabbing the head and I guess they just hold on until the victim is dead. Out of our girls that were killed, one was partially eaten and the rest just had their heads...
The rotten little varmit got in through a 1" knot hole in the pine door of the coop. He proceeded to curl up in the hay under the nesting boxes after he had gotten his belly full.
