I came home from work and found pieces of my black chicken Magic. her carcass was half pulled through the fence and most of the meat was gone from her bone one leg torn off and several areas of large skin and feathers A truly terrible sight . What could have done this. My chickens free range during the day and coop at nite, I bought a trap and hope to catch the murderer but it would help if I knew what it might be. Any Ideas?
