Well they may stay on the roost a little longer... but turkeys are going to do their thing. Heck, the gobblers up here were strutting and trying to find a hot hen with 3 feet of snow on the ground a month ago. Your only problem will be they may sit on the roost a little longer and not be so vocal. Our season doesn't open for another 17 days. You think you got problems... up here they're still all flocked up big time in their winter mode. It's either they're in your woods or they all moved where you can't hunt. I've been following a flock of 15 for a week. They've moved a mile away and seem happy. I might not beable to hear a bird opening day.
