Personaly I wouldn't try it. I've had back luck of walking in on birds on accident, and it seems they get extreamly pressured and I don't see them for a while. But if I was to try it, I would only do it once, and try my hardest to make it work so you only have to do it once a season. I know it's a fall tactic, but I've heard in the fall the birds become "dumb" if thats even possilbe for a turkey to become. If you try it, let us know how it goes! good luck
