What part of central NY do you hunt? I hunt a lot in New Berlin, NY in Otsego County and I know last year they were real henned up near us. They would gobble on the roost but then once they hit the ground they would go their own way. However turkeys usually have a set travel route, so you might want to spend some more time scouting and figure out where they go off the roost. Its a lot easier to call a bird to a place he wants to go, instead of calling him away from his normal route. If you are sure hens are the problem you might want to try to call to the hens instead of the gobbler. The best thing i've found is when a hen starts calling immediately cut her off and call over top of her. If she is yelping interrupt her yelp with one of your own, but make yours a little louder and a little faster. If she is giving you that aggrivated cluck, start cutting back at her. A lot of times you will make those hens so mad they will come marching in looking to teach you a lesson, and sometimes their boyfriend will follow.
