Last night something got into the chicken yard and killed 4 eight week old Marans. My husband found them scattered around, one was even in the chicken coop. He told me that the little ones chest/crop were eaten. The adult hen was fine. We have everyone locked in the coop tonight. I will probably always lock them inside now. Was this a raccoon? We live in a rural area, and I have seen foxes, among other critters.
