Lost three hens

[mathchick3]

I lost three free range hens in one night. They were my white girls (two silkies and an easter egger). There were not secured in their coop which was the norm. There were feathers in three different locations in the yard but no carcasses to be found. Any help would be appreciated. I am devastated.
Thanks!

Fox, dogs, coyotes, are likely. Usually coons will leave residue.
