My wife and I are new to raising chickens. We have had them for 6 months now. Sometime this morning we lost our first hen. When I came home for lunch today I found a hen dead in our fenced in area. Something killed her between 8 and noon. She was decapitated and her side was ripped open. There wasn't a lot of blood, which is really confusing to us. What ever it was didn't go into the coop and cause any trouble in there, thank goodness. The predators that I have come up with that are most likely to have done this are a great horned owl or a weasel. Since this happened during the morning I am leaning more towards a weasel. We live in southern MI, not really sure if there are any weasels in our area or not. If anyone has any guesses as to what could have killed her please let me know. Thanks.
