You are having the same problem I am having here in Ohio. Somedays Turkeys gobble and others they don't. When I face problems like this, I like to go the edges of fields where I have seen turkeys in the past. This has been a successful tool for me, I have killed three nice birds by using this tactic. Be patient, good things come to those who wait. I have also found, that the quiet birds are usually significantly bigger... longer beards and spurs and weigh a bit more than your ordinary tom.
