Last night, I returned home to find one of my four chickens dead in my backyard. Something had attacked the chicken and left it dead where it lay in a pile of feathers. I examined the deceased chicken to determine what preadetor caused the death, but I am now more confused. 1. The chicken had two dime/quarter size holes on its back behind the shoulders, slightly under the left wing. 2. There was no blood, anywhere, even around the puncture wounds, or on the ground in the yard. The chicken was still warm, but there is no blood in the body. 3. The neck was broken. Furthermore; 4. The yard is basically impenetrable for a dog. 5. I have seen raccoons in the neighborhood, but they have not caused a problem in the past 6 months. Can anyone help me determine what kind of animal may have killed my chicken?
