my spot i was hunting up by college was having that problem....first day i hunted it they were going BONKERS.....then the last 2 or 3 or 4 times i hunted they didnt say a peep....i heard their wings as they fly down one day...never said a peep and never had the slightest intrest in calling..alot of guys called it a "gobbling lull" i guess after they breed and do their thing that they shut up for a couple days or so....mine went atleast a week or so though...i left and am home so i dont know if or when they fired back up.....
