What R.H. witnessed seems about right with my experience. The usual hen breeding calls aren't normal for fall. But, the sound of young birds, lost or distressed young birds, can be effective, especially if you've spooked a flock. Some people intentionally bust and scatter a flock and then use lost hen kee-kee runs, and clicks to call them back together at the hunter's location.
Seems to me that if you can scatter them like that, you could have shot one.
If/when I can get fairly close I like to sit and scratch at the leaf litter and make soft (contented?) clucks and purrs. Try to get the birds to think a real honey hole of good ears has been found.
Careful with the young bird sounds, be alert, other things like to come in for young turkeys.
