about 15-20 years ago there were some wild turkeys in my area that had white wings and fans. The bodies were kind of a reddish brown color. I personally saw two hens and one adult tom. One hen and the adult tom were eventually harvested. The DNR claimed they were just a genetic anomoly, not a wild/domestic hybrid. My former boss shot a albino tom near Ettrick, WI in that same time period. The only thing that wasn’t white was the head, the beard and the feet.
I’d say this bird is wild. The best way to tell is the length of the legs. Wild birds have long, lanky legs. Domestic birds have stubby legs. Same with the beards. Wild=big beard, tame=stubby beard.
Lots of cool things in nature!
