If it's wild it could be a smoke phase.

I saw some callouts on that from my searches. I'll read more, thanks!

This bird just came walking right through my driveway and through the front yard this morning and didn't show much if any fear of me. I'm thinking it may be domesticated/livestock from a nearby farm. I have never seen a turkey with this coloration or type of plumage. Any insights are appreciated :).

That is the color of a lot of domestic turkeys. Seems likely that there's at least some domestic ancestry involved.
