Went to the coop early this am to find one of my large roosters dead. What ever killed him ate only the crop area it appears. His head, breast, back, and feet was left behind. This is just terrible. I have not been having a problem with predators up until this point. We actually do not even close our coops up at night. The free range area is closed off with fencing at least 4ft high. We have had a problem with chicken snakes lately and my chickens have been steering clear of the coop at night. They will from now on be in a closed coop at night. Any suggestions will be greatly appreciated. Thanks in advance!
