As a rule, most times you can start calling about a half hour after you break them, but that depends somewhat on when you break them. In the last two days I've busted 3 flocks, 1 late in the afternoon and two in the mornings. The flock I busted late in the afternoon started kee keeing as soon as they landed, it took the brood hen about 10 min to start clucking. The flock this morning I busted off the roost and it took them about 45 min to start clucking with a couple yelps. They were very vocal this morning, a lot of tree pitting, and a few deep cutts, and a couple yelps. The flock yesterday morning was a flock of gobblers, as I was moving in, I busted one and then rushed in to bust the others. It took almost 2 hours before I heard a couple deep clucks.
