I love the fall hunts. It's an opportunity to see flocks of turkeys, hear their vocalizations and to watch how they interact.
There's certainly nothing wrong with an ambush but it's much more fun to "bust them up" and then call them back. It's really very easy to do, in my experience and it really helps to increase your confidence.
If I know there are turkeys in the woods (and I try only to hunt those places) and I've not had time to scout which I seldom do in the fall, I may just sit and kee-kee after sunrise. Many times that will produce some birds and many times they'll come in very quietly if they've not been separated from their flock the previous evening. If they have been, they'll come in one by one and will answer my calls.
If a small group comes in, I'll rush them, shoot in the air, bust them up and them sit and call them back. I love to hear them answer my calls and love to imitate what they are saying.
If I see a large flock, I'll get as close under cover as possible and then rush them, barking, yelling and/or shooting in the air to get a good bust and then call them back.
