I was set up on about 15 birds, 5 gobblers and a few jakes and hens. The birds roost in sight of my setup, about 150 yds away on the edge of a bean field on another property. At about 6:00, they fly down in the field and strut right by the fence dividing the properties. They will gobble at my calls but I can't seem to get one to break away from the group. What would you do?
