Ya never know how fast they'll come or if they'll come. Sometimes they are on ya in a minute or 2 or it may take 3 or 4 hours. If ya got nesting hens you may want to put in a little more time in the morning, the hens go to nest and the toms start serchin for that call you made at first light. I've shot a lot of turkeys between 11 am and 2 pm. If ya keep yer butt in the dirt long enough it will happen sooner or later. Good luck to ya.
