ManFall,
Wherever I hunt it's the same. If you see them early, just do whatever you can to make positive sure they see your decoys and hear your calls. If they move off, no problem. Continue to call every half hour. Then at about 10 AM the hens will break off and go their separate ways to sit on their nests. That's when the toms will come to check out your dekes. Works like money for me virtually every year.
