RE: Call shy turkeys?
When it comes to those stubron call shy toms , try diffrent tones of calling they respone to a soft sweet sound or an aggressive excited hen.
If you can the boss hen to come to you then the tom will follow her to your location a another suggestion would be the use of decoys.
If the tom sees the decoy ( feeding hen ) it might entice the tom enough to come in close for the shot , if that doesn't work then you might want to try a gobble call with a jake decoy.
