i know it was last year but i may have to deal with it again and i never had this then, i lost about 4 hens last year to something i found one riped up one month one the week after and one a moth later then a couple of moths later i went down to my hens and found my welsummer omlete ripped up out side the shed there was feathers every were and then was just her bones with al the skin and insides eaten and her head was gone?

I think a dog is the culprit

Daytime - dog or hawk
Night - coon

A raccoon or opossum might have done it.
