My cousin was bushhogging at the place we hunt in Columbus, MS late last week. He waited until after July 4th since that's the rule of thumb. He blew a hen off the nest with the tractor so he immediately left that area. He went back over the weekend on foot to see if she came back, and she was back on the nest. Looking at the poult pictures I've seen she must have been a late nester or maybe those eggs are not going to hatch.
