We found my full grown Araucana dead this morning in the pen. Her back end was grossly mutilated. Our chickens are in a fully fenced coop unless we are outside with them. They have an enclosed nest area and the chicken wire is buried to keep critters from digging under. But something happened anyway. There are no signs of damage to the fence so it doesn't appear that anything got into the fenced area - and the rest of the girls are just fine. Could something get it's paws through the chicken wire to mutilate her so badly?
