Are you hunting during the 'penned up' time when the Toms found their mates? Or, are you not hunting out of a blind?
I hunted a large farm pasture with a long running high wooded ridge line. I set up my blind looking out into the field and set out some decoys out in the field. I called, occasionally. At different parts of the day, I would hear Turkeys in the woods. My set up made them fly out of the woods and into the pasture. from there it was a done deal!
