DDT, are you setting up in a clear field or in the timber? If you are in the timber does the pretty boy startle the incomming tom when he spots him so close? Sorta like a deer decoy in the woods?
If they spot him from afar and won't come in I would guess its a dominance thing, but if you are set up in the woods it could be a startle thing. We had one in KS working into the hen decoys. When he came around a dead fall and spotted the PB he was gone. There is always teh posibillity that this bird saw us move in teh blind too, but we'll never know. Just a few more inches and I coulda had a shot.
Take it for what it is worth, I've got a whopping eight hunts under my belt. Thats not eight years, but eight times in the blind.
