That will work great if you hear nothing try the coyote call if they are there they will answer. To get the best possible odds of getting a bird I would locate them the week before then get close enough to here them just before light. Stay quite and when you hear them fly down Mark the landing site,roost area,travel routs and follow them to the strut area, then sneak out. You now have multiple set up locations, the best way in and if you spooked them they have a week to settle.
