It varies. In previous years, the hunting ended at noon in MN and WI but now it's gone to 5:00pm in WI and sunset in MN. At least I think it's still 5pm in WI. Anyway, I've taken a few birds in the afternoon around 3pm, taken a few that have flown right off the roost to me, a few in the first hours of daylight, and then a few in that 10am to 12pm slot too. Since we only have 5 days to hunt, I like to get out there early at 5am as sometimes they'll start gobbling at 5:15 to 5:30, listen for awhile to determine where I want to go, and make the move. I quit using decoys so moving to the birds is easier.
