These exist in the midwest also. I've hunted them. Damn hard.
My parents had domesticated turkeys for awhile (various breeds, none of them found around here since they were either white, black spanish, bourbon red etc., not the kind that sit in cages their whole lives fit free-range ones).
One time a domesticated bourbon red hen ran off in the spring and joined a flock of wild turkeys (the kind discussed in this thread) for an entire summer. She eventually came back for the winter, with babies in tow.
