So the other day my wife went to let the chickens out and yelled for me to come out. We had 9 total chickens, and all but 2 were eaten/killed. Not all of the chickens were eaten. Some were just killed and had marks around their necks. All that was left was the wings, rib cage, head, and feet. I'm assuming the intruder crawled up and got in through the soffit of the coop. I am currently working on sealing the coop up really well as we rebuild our flock. I'm assuming it was a raccoon that climbed in.
