Archery is a different ballgame. I almost always use dekes when bowhunting them. I like two hens and a jake, maybe even two hens and a strutting tom decoy. That strutting tom is a homerun/strikeout move. You score big or you scare ’em big. It’s capability to draw birds from distance is worth having one IMO. Whether they eventually commit or not is a different story.
Footage from the morning of our video hunt (footage we didn’t get well as it was behind the blind) had an old, cool-customer of a tom come in from behind. He roosted separate from the rest, he gobbled thunderously from the highest point in the valley, and came in silent (of course). He looked at the strutting tom deke for all of 5 seconds before going right back where he came.
A single hen is a real stealth play. I’d do that if the birds have been hunted before. Also wise if you’d take a jake. In certain situations like that, I like to use one or two hens slightly hidden on a field edge or meadow edge. Lots of times when a turkey sees them, then doesn’t see them, then sees them again…..I think that gets them to come in pretty close.
In all reality, during the last two weeks of the season, many of the toms will want to be with hens that don’t want to be with them. Getting them to check you out usually isn’t too bad on good property with enough days. This time of year I consistently call in more birds (within gun range) than any other time of the year for me. You’re also way more likely to be able to draw a tom away from his hens during this time of year. The trick is always getting them to get within bow range at this stage of the game.
Narrows in fields, bottlenecks like ravines/draws, and or field entry/exit spots pin them down to a certain yardage which I think is more critical than decoy number or placement. Also, use that blind to corner them into a field or setup mid “structure” to get 20 yard shots on either side. The more I bowhunt them, the more I respect the guys that pick one or two setups that are turkey killin’ spots and stick it out. I have a hard time doing that personally as it’s not as fun for me. I enjoy the cat/mouse game with the shotgun too much, even if I know the former is more likely to fill my tag at the end of the season.
Good luck!!!

It can be done, but chances are 1 in a million. I would say use a hen decoy and limit volume and calling once you see how a gobbler. There are better answers than mine but i would say bring one every time but keep it in the blind
