Turkeys should be at or near the middle to end stages of breeding...with toms looking for hens to breed. Hen decoy(s) would be nice, but not necessary. Hunt near the roost early and see if you can call one in right off the bat. If this doesn't work, then get into an area where turkeys move, and call. If you get a response, be ready. No response, move another hundred yards and try again.
