One of my ex battery hens got killed last night. Obviously, she didn't come in with the rest of the flock. Found her this morning in the barn. She was eaten just a little in the breast area. Any idea what might have done that? We live in a semi-rural area. We have coyotes, raccoons, foxes, a cat and two dogs. The one dog is on a dog run away from the chickens, the other doesn't go near them. Both of the dogs were barking at something last night.
