Wish I could help you out. But, I hunt turkeys the same way I hunt deer. I never call or use decoys. I scout birds and pattern their normal routines and set up at an ambush point. Most turkeys use the same routes almost daily unless they are disturbed. The bird I took this morning was taken from a one man chair blind that I sat up last Wednesday afternoon. This blind sits in the wide open in grass that is no more than two inches tall. But, the turkeys follow a woods edge that is less than twenty yards from where I sat up the blind. Knowing where they travel is key IMO. I've never hunt near a roosting bird so very seldom do I get a shot right after fly down.
