if you have permission to go to where they are, go there before sun up and be set up when they get there, if not
as you said, they won't come to you, MOVE on else where, lots of turkeys out there, why keep messing with one's that don';t want to be where you are?
option 2, if the place there at is AGAIN< open to hunting by YOU< you can always go in and BUST them up, make them leave in all different directions
and they try and call them back together, as one might do in the Fall, but this, again might make them even harder to call too, pending how much time they have hearing you call,
turkey's can be pretty smart critters and learn who is after them to a point( sounds your making they maybe can ID) they talk to each other daily and know new birds as to there regulars! IMO!
