Well it definitely exist.

The difference being, there's a lot less doe going into heat than there were earlier. It's just the later born fawns or early fawns(which ever you want) and the few that didn't get bred or take the first time through. Most people don't even notice the difference of going from post rut to second rut to post rut again. It's a whole lot quieter time. Bucks are still looking but they've been beat up. A lot of them have gotten themselves killed to. Just some trolling and following and we're back to scrape lines and food.
