Turkeys do try to roam as far as they can, so mine never totally free range, I like controlling my turkeys movements, I don't like them running amok or climbing in my trees, I put mine out and when either I or them have had enough they get put back in their spacious run.
There were quite a few posts this year about turkeys just showing up in people's yards, and a few about having to go find the turkeys. I don't think turkeys are as bonded to a coop like chickens can be, and they always need reminding. I think if it's just two or three than it's not as bad, I have fifteen and they form quite a rowdy band when free ranging.
