Have had my girls for almost a year now. This morning found one dead, head gone, innerds pulled out and eaten, pretty clean job besides the feathers laying about. My coop is inside a fenced orchard (6 ft fencing). The birds have the walk of the orchard in the day. The fence perimeter was untouched, there is a foot of hard snow on the ground. A light dusting of snow covered the ground, obviously post event. No tracks. I bought a live trap, I baited it with the carcass and some cat food. Whatever is in it in the morning, won't be alive shortly after my arrival. I closed the hens inside the coop for the night. I figure a racoon got her, only assuming because of the clean kill. There are eagles here, but don't see them in the winter. Only other animals about are domestic dogs and cats and coyotes, but again, the kill site was very precise and no dogs could pentrate the fence unknown. Any ideas? I will keep you posted on the results.
