My biggest piece of advise is to back off on the scouting. Don't pressure the birds at all. Watch from a distance and don't let them know you are there. Next broaden your call range. Clucks might be all you need as they are a very common sound. However they don't caarry very far. 41 days is still along time, and patterns might well change. Keep scouting and try to set up near where they come down each day, or along the way they move after fly down. If you are going to use decoys a hen would probably be helpful since that is a toms driving interest in spring. The jake and hen togeather can create a dominance reaction from a mature tom.
