Today I found one of our two chickens dead in the run under the coop. Her crop was open and her chest muscles exposed. The coop is inside a 6 foot fence, inside an electric fence (not turned on at the time of the incident) and the whole thing is inside a bigger 6 foot fence that goes around our yard. There were no areas where an animal dug under. Our other hen was inside the coop with some scratches on her comb, but otherwise unharmed. It happened some time between 10am and 1pm. I have never worried about them during the middle of the day inside the fence before, so this a whole new ball game. It seems like a raccoon attack to me and I am worried that is could be a rabid raccoon. It doesn't seem like a hawk would go inside the run and under the coop. Any thoughts?
