MB gave some good advise. If you have the caller and decoy right next to you, the 'yotes zero in and run right at you. If you move, they'll spot you. At least set the decoy (could be something as simple as a feather on a string tied to a stick) a ways away from you to draw their attention away.
You may try baiting too. We've done that with some success.
This time of year it's tough to get them to come out.
