We caught a raccoon! My Dad an I were out checking the traps last night, and we surprised it as it was leaving the coop. It was going after the eggs in the traps, and it did manage to get them without setting the traps off. Dad shot it, so that's one down, anyway, but I'm not convinced that the coon was what ate the other chickens. Both chickens had their heads and crops intact (aside from some damage that was, I assume, from the predator initially killing them). They were both eaten away in the hind quarters, near the vent and legs. The Silkie was very small and easy to carry, too. Has anyone had a predator attack like this, where the pattern didn't match?
Could there maybe be two predators?
Also, the chickens are all still being kept in the barn at night, so, thankfully, the coop was empty when we caught the coon.
