RE: Turkey set-up opinion NEEDED
Assuming Brox is bowhunting and for Jeff,
one of two things have to happen and I know Jeff isn't going to like the later, one, you need to visually stimulate your gobbler to come into bow range or why else would he be close to your blind except for a well positioned ambush, or two, you need to call them in and still call when they are insight of the blind but not close enough for a shot. Now the later with no decoy is tough because a gobbler will know exactly where that call is coming from, he looks, he sees no hen, may or may not pay more attention to your blind however, he's not likely to come any closer to something he cannot see.
I'm not a big fan of decoys however for bowhunting, they are pretty much mandatory unless your ambushing them.
