Turkeys don't usually like to walk in tall wheat. They are just like us...I'd rather walk down a paved sidewalk than in brush 5 ft.tall. When wheat gets above 18" tall or so ,maybe shorter than that,turkeys will change habits and strut in pastures etc. Right now in some of the ground I hunt wheat is about a foot tall....depending on rain etc.I probably have 2-3 weeks more hunting in those fields. It also depends how thick the wheat crop is.....if on good ground and good moisture crop is real thick it's hard for them to walk through.
