I would think turkeys would be there if the woods aren't real thick. Turkeys don't need flat land, never met one that minded a hill or being away from a farm. They've been around a lot longer than any farmer and think they can do just fine in the woods. I would just think they might be more spread out. Try getting their at daylight and just listen, maybe he'll tell on himself. It would be hard to find tracks in leaves in a large block of woods.
