So we have been letting our chickens range free during the day. They spend most of it under one of two big pine trees. Have had no signs of any predators. Came home tonight, the sun was setting but still light out / no later than we've gotten home before. Saw a few of them (had seven) bopping around the yard when I pulled in, thought nothing of it, they usually come over to see if they'll get treats. Told our girls, as we do every evening, to go check for eggs as ours tend to lay under the tree versus the nesting boxes. A few minutes later, one is sobbing that Midnight (the easter egger) is dead. When my husband got home later, he went out to inspect, and the head was pretty much gone, insides ripped open / all mangled. The odd part, to him, was she was under one of the big pine trees. So he doesn't think it was a hawk, but not sure why whatever the hell it was didn't attack/get to any of the others. And of course, I feel bad, as we stopped on an errand on the way home, but as mentioned, we got home no later than we normally do (last night was half an hour later than tonight, and they were fine) We're a little afraid now to let them free range as we thought being in/under the huge pine tree was a safe place.
