If you're close enough to break up a flock, you're close enough to mow one down with a super full choke. Sure, they'll cluck to regroup, but not in the sense of spring mating, etc... not sure where you were going with this.
If a turkey gets separated from its flock they use calling to get back toegther. If you break the flock up they'll call and respond to calling.
Fall turkey hunting with dogs and calls is an old tradition.
