I have had good luck at all different times of the day but the most have come early to mid-morning. I think the best time is whatever time you can be out there even if you don't take a bird!!! Hunting is sometimes about what you see not what you shoot, in my opinion! One of the best days I had last year I didn't even get a shot, but I got to watch a great show. First, I got to watch a good fight, then an hour later I got to watch a tom work and mount three hens... all while the losing tom watched! I learned a lot about turkeys that day.
