RE: best time to thin out does and does it hurt anything?
If you take the does early, the bucks will spend more time cruising, looking for does...
25 years ago, I put a hunter in the Killing Field...He saw 37 deer, no antlers...This was during the peak of the rut...I started agressively killing does....In the same field last week, we would see 8-10 does each evening...Killed 2 nice bucks, cruising....
Bucks have no need to "look" for does when the ratio is too high....Inferior bucks also get to breed during this time, by lowering the doe to buck ratio, the better bucks are taken by the does....
In most areas of NC the ratio is way out of wack and it will take 3-4 years to bring it down to where it needs to be...
