Welcome to the turkey woods!! I am not an expert by any means but will tell you a few things that have helped me. I started hunting them back about 1985 and had no clue what I was doing out there. I made alot of mistakes and the birds never seemed to appear when I was calling. I'm more of a run & gun type but am learning to be more patient and sit longer...especially after calling. I've called from one spot and then decided to move only to have a gobbler spook that was coming in silent. So, when you call from a spot, wait at 20 to 30 minutes before moving on as a gobbler may come in silent. Also, I've killed alot more birds with clucks and purrs than yelps. Example-I saw two gobblers strutting in a pasture and so I snuck around a bluff, down a logging road on the backside, and got into the pasture. I poked up over a rise slowly to see the top of one fanned out about 50 yards from me. I backed off, got my vest off, and crawled up with a slate in hand and my gun. I yelped on the slate and got a response so I got the gun up. There was only about 2" of grass in that pasture so I had to be ready if he came over the hill. Nothing came so I yelped again and he gobbled in the same place. I did this a few times but no change in position. So then I switched to a few soft clucks and a purr. Suddenly he gobbled closer so I got the gun up. He came over the hill and I shot him at about 8 paces. Another bird in Wisconsin did the same thing...yelps would make him answer but he wouldn't come any closer. Then I clucked softly and he came in.
Forget that calling you see on TV. They keep yelping to get the birds to gobble for the camera but in reality, I don't think you need to call nearly that much. Once a bird knows you are there, he won't forget. Even if he goes off to mate with a hen he may still show up later in the morning. Staying put for a whole morning and having the patience to do so can pay off for you too. If your lease isn't that big then I'd suggest building a blind in a good location (Where they strut or near water source) and setting up there. If you have limited amounts of land you don't want to go kicking the birds off the property by moving around too much. One tip that I can give about using decoys that worked for me was to put the jake right on top of the hen to make it look as if he is ready to mount her. Last spring, I took a buckwing jake decoy and put it over a hen. I took the stake out of her and put her right on the ground which is natural when they are ready to mate. That gobbler will jump up on her back when she is sitting down on the ground, step on her repeatedly, and then they mate. So anyway, I had a gobbler come in from the side of the jake, walk up, and stomp on my jake. His next stop was the dinner table. Also, remember that you don't necessarily have to use decoys to kill turkeys. It helps to divert their attention away from you but it can also make a gobbler hang up on you. I've had that happen more often than not as where I hunt they get alot of pressure. I've killed more birds without decoys than with them and I think it's more of a challenge to do so since that bird is looking for you and you have to get the gun up without them seeing you. Well, I'm rambling so hope this make at least some sense...
