RE: Problem Turkey
tell thgem you are the new boss and you'll kick his butt and take his women...
Use a full strut decoy or stuffed real thing, and potentially use some fighting purrs and gobble shakers. you may scare off the sub-dominants, but the Mac-daddy may very well pay you a visit, they are very very territorial.
I'd set up a strutting gobbler decoy behind 1-2 hens and see if you can get their attention. If they don't come in sight, try some excited cuts then a gobble. If still no takers, move and break out the fighting purrs.
A very accomplished turkey hunter (been on several outdoor shows calling) told me very recently that to kill a big dominant bird use challenges vs hen calls, strut decoys, etc...
