Put up a game cam so you know for sure.Possibly fox? Skunk? Possum? I thought fox would take what it could to the den. All these were still here and killed for it's best pieces.
When you get the area secured, if you want some of my meat mutts let me know. They are broody raised, so they are wild. I have too many right now. I have 6 I could give you..about a week old that could be tamed down if you got them now. Not sure of sex.
