A word of caution on busting them into a scatter and calling them back. This will work for hens (if hunting them is legal in your area) and on jakes, but old toms usually just don't "give a real damn" about getting back together. Since I can't hunt hens in the fall at my WMA, fall hunting is a jake hunt for me. I agree with the guys who answered about the roost. You didn't spook them off the roost so the roost shouldn't be haunted for them. If they don't roost there again for a while it's just they have moved a bit, not that you boogered the roost.
