I don't even know what questions to ask /answer in order to figure it out. Here is the repeating story. I get to the roosting spot about a half hour before sunrise. They are roosting to the west of me, I set up under a cedar tree/behind a hill. I can't get any closer without being seen and scaring them off roost. I made that mistake already. I call, they gobble. A hen calls, I wait a little bit, mimic her call, they gobble. They gobble, I yelp, they gobble. I've tried calling a lot, calling, a little, only calling after hearing a gobble. The end result is always the same. Shortly after sunrise, they come off roost to the west. Toward the real hen. They continue to answer my call right up until they are out of ear shot. I hear them getting further away each time. Am I making some huge glaring error that I can't see? Is it possible that there are enough hens in this flock that there is no reason for a tom to look for one that he can hear but not see? Anybody have any advice?
