so i went scouting all morning, i'd drive around my local area and once i see a flock id get out and sneak up until i was about 100 yards or less away (un-noticed). i would let out a few clucks, yelps, purrs etc... the damn turkeys will not react or respond, but they are strutting already and my turkey season isnt till the 1st of may, what am i doing wrong? the turkeys have no response at all... i have two weeks to figure this out, and its vaguely frustrating.
The advice you've been given so far is good, but I would add one thing.
Even if the turkeys aren't spotting you, your tactic is a waste of time. You say you see a flock that gobblers are displaying for. That means the gobblers' attention is on the hens in that flock. They aren't likely to pay any attention to your calls. The old saying, "A bird in the hand is worth two in the bush" applies here. When a gobbler has what he wants right in front of him, he has no reason to respond to you. He hears you, and so do the hens.
Occasionally he will gobble, especially if the hens start leading him away. If they lead the gobblers away, they are responding to you, although not vocally. By moving off they are telling you that they don't want you around. If a gobbler gobbles to you in that case, all is saying to you is "We're moving off -- if you want to come you better come now."
Watch the flocks and see where they come into the fields in order to get an idea where they're roosting. Watch them when they leave to get an idea where you should hunt in late morning.
