If you know where they roost i would set up fairly close and put decoys out. When they fly down they should be able to see them.

This early you kind of need to be where the birds want to be. They decoywill most likelyspark some curiosity in them and help bring them in even closer. If you have a full strutt decoy i would recommend that. We had good success with them in KS last weekend.

Good luck!
