I' ve never fall hunted, but Lovett Williams has described a successful scenario. He suggests you bust up a flock, sit and wait a half an hour, then call. I think an alternative is to bust them up the night before on the roost, which would be easier, if you know likely roost sites, than to run in on ' em a hootin' and a hollerin' as others here would suggest.

If you bust ' em up the night before, you get in the middle of ' em and make assembly calls and kee kees in the a.m./dawn' s early light.

If you bust ' em in the day, I think you hunker down and wait a half an hour to calm ' em down, then use kee kees and keekee runs, as well as gobbler yelps, and maybe assembly yelps, though I understand each mama hen has her own assembly yelp, so I don' t know what good assembly yelping would do.

Else you can waylay them along their path and whomp ' em, if you know their routes and habits.
