Unfortunately, one of my chickens was killed today. I only found a clump of feathers attached to skin in my kitchen (I am assuming one of the dogs dragged it in). There was no other evidence that the chicken was attacked. None of my other chickens were harmed. The chickens free range in our fenced in yard. I'm sure some of you will say it was our dogs, however they do not bother the chickens. We have had the chickens for a year and a half and have never had any problems. We do live in a wooded area and recently saw a fox in the yard outside the fence.
