Not sure if there " right " way to roost a turkey. Is it or an open area where you can see them heading into the woods to fly up ? I've used an owl call or crow call at dusk just about what I think is fly up time if I can't get a visual on birds. Or just a simple series of yelps to get them to answer before or at fly up time. And a fly up cackle and maybe I'll toss in the slapping of my hat off my leg for the wing sound. In my experience I've never gotten them to answer when it's gotten completely dark , and I've never used a coyote call to get them to shock gobble. Considering the yote population here in NH. And trying to find potential roosting site during my preseason scouting helps alot.
And of course they may not answer at all when attempting to roost them no matter what you use.
