What kills and eats the back area?

[tnchicken]

Something attacked our small flock of 8 hens around dusk. 3 were dead with the back area eaten out (one found inside the hen house). The others had been attacked and wounded all around the tail and back area???? I think it happened within an hour window of dusk. Any ideas????

Thanks

Foxes take the carcasses away, I would think perhaps a coyote? Or a dog. Sorry to hear about your losses.
