Rickey, I haven't heard a gobble within a mile. But like you, they must have a nest up in the thicket behind the house. They would often roost within 100 yards of the porch. I've sat out there many nights until dark and hunted a few days behind the house and have heard nothing. I hunted the roost one morning and they didn't come off the roost till I busted them at 9:30 am.
It was also a warm clear morning. Never seen anything like it.
