We are not sure what it was. I came home this evening about 7:30 and noticed feathers all around the yard. We had 26 chickens. I could tell immediately that one was dead and another was pretty hurt. Many are missing tail feathers and rump feathers. A few have gashes and punchure marks on their backs. We have a privacy fence around the paremeter of our property and the chickens free-range during the day. Can't find any tracks of any animal but wonder if it was a dog. Just don't see any place where it might have tunneled under. Any body have any ideas what it might be?
