Let me preface this by saying that I'm new to chicken keeping. Last friday something got into the chicken pen and killed one of our chickens and mortally wounded another. The strange thing is that the fight appears to have taken place both in the fenced in area where the dead body was found and inside the hen house itself where I found a huge pile of feathers and some blood. I know very little about the condition of the dead chicken (my brother handled it, and I really don't want to know!) other than the body was mostly intact, laying on the ground around the side of the hen house (but in the fenced in area) and chomped on the top side only. The one that was mortally wounded was found outside of the fenced in area in some brush. This old coop had a 9 foot fence around it (except in one small area) and no top. We have since re-done the coop so that it now has a fencing top on it and is 9 feet all around with no possible holes. We piled up logs all around the interor and exterior of the fencing to discourage digging animals. Any thoughts on what might have gotten to the chickens? We were betting on a bird of some sort until we saw the feathers in the coop. Any ideas?
