Redmag,
Do you know where they're coming from? Try getting in between them and where they want to be. You might try placing your decoy (hen) where they were strutting. Then find a tree to the side, between where they're coming from and your decoy.
The idea is that they'll look towards the decoy.Use soft calls, and scratch the leaves & ground. Once you hear them coming your way, shut up and let them come looking. Look sharp with your eyes, not your head. You may have a sub-dominant bird try to sneak in silent.

Good luck.
