My 6 Ameraucanas have been happily free-ranging for a year, going into their electrified pen and coop at night. Paradise was lost yesterday when one of my hens was killed during the day. Here's how I unhappily found her: She was behind some bushes, with the feathers and skin stripped off her sides and back and, except for a few small scattered pieces, these parts were gone. Her neck may have been broken. The rest of her was not eaten. Here are my questions: What animal could have done this? I've seen a feral cat around. Is that a possible culprit? Could I have surprised a predator in the act, which never got to finish its meal? And last of all, can I continue to let my chickens free-range? I hate the thought of confining them full-time, since they love their freedom and I love watching and hearing them as they make their daily rounds.
