Any time is a good time to hunt Wild Turkeys and 10:00am- 12:00noon is a great time to get one, coming. Hens are sitting so the Tom is vulnerable to calls. The trick is to be close to where the hen is most likely nesting, cause that's where the tom is going to be. Glassing fields on your hunting areas helps a lot and the birds will be on the same area the next day.
Just one advice avoid using decoys. The intense sun shining on those decoys during that time frame is a handicap.
CHEERS and good luck...louie
