If you have them patterned you know approximately where they will be if not set up at strut zones, roost if you know where they are. If you only know the general area get there and use yelping and cutting.
Check with your game warden and see if you can be in the woods SCOUTING AND NOT HUNTING (no gun) during the time you are not allowed to hunt, that could really give you a leg up. I bet legally you could, doesn't hurt to ask.
