OK, so I should buy 3 or 4 ammo types and test to see which patterns best in my gun, sounds like. Check. Get up well before dawn. Check. Decoys not really necessary. Check. But which sound do you make at which time (gobble, cackle, purr, etc.), and in what sequence - and it depends on whether you want a hen or tom, I take it, but which for which. Any other details that might help me out?
So if turkeys hate crows, then I assume they'd steer clear of them. So do what, call in one place to run the turkeys out, then run to another place where you've driven them?
