Scoot, even the turkey don't know what he's going to do when he wakes up of a morning. They'll usually do the opposite of what you want them to do. Now if you could get there early enough to set up a decoys before they can see, and make a couple of very soft tree yelps, you might get them to pitch down where you want them. I'm guessing they could see your decoys better in the picked corn or clover field.
