This will sound a half a bubble off plum, but IMO, if you want more roosters in the fall, you have to kill more roosters in the fall. What I mean by that is roosters are bigger, stronger, and more aggressive than hens. As a result, more hens die each winter than do roosters simply by the roosters pushing the hens off food, pushing hens out of cover to be more exposed to the elements, and basically bullying them around all winter. Just watch a group of pheasants feeding in a field and watch what the roosters do to the hens. When a hen finds a cob of corn and starts to feed, inevitably a dickhead rooster runs over and kicks her off the cob and eats it himself. Just look at a group of pheasants hiding behind a piece of good cover in a winter wind and see where the roosters are and where the hens are. The azzhole roosters are in the dead middle and most protected while the hens are on the outside and more exposed. Research confirms that hens suffer significantly more winter mortality than do roosters. I think the limit needs to be doubled or tripled. Each hen saved is 6-10 chicks hatched in the spring. Half of them being roosters. Just a thought.
