Such a shame, I am so sorry. What was interesting to me was that the predator didn't bother with the head or neck, just left her with that huge gaping hole. Our chickens have been free range for their short 9 month life span and unfortunately we will have to keep them locked up from now on. Our run has a roof over it, I'm hoping that will be helpful. It's such a loss, they were so happy roaming about everyday! Every time we keep them locked in they just wait by the run door all day, waiting to be let out. I need to research some ideas to keep them busy.
