In addition to my own chickens, guinea fowl and peafowl I also take care of my neighbor's chickens and guinea fowl. This morning I went by his farm to check on his chickens and found his rooster dead on the floor of the coop. There was no sign of entry...the two hens who reside with the rooster were fine. Whatever killed the rooster devoured his internal organs...the rest of the carcass was left whole. What type of predator would do this?
