Dont give up on one that doesnt come in first thing. I call 9-10 magic hour. After breeding hens they tend to wonder away looking for more receptive hens. Dont over call.
Sometimes the best call is raking leaves with hand.
It will become the most frustrating thing you will love to do. You will always second guess yourself on strategy. Thats what makes it so fun.
After you get a few hunts under your belt, try and go with an experienced hunter.
I would be glad to go with you a couple of times mid season, and I'll leave my gun at home.
