In college they told us that in a perfect world, does birthed twins. One buck, one doe. Ideally the herd should be 1:1. To predators, meat is meat, buck or doe. Without the influx of predators, and hunters and the regulations we have to follow, up until recent years, it was standard to shoot mostly bucks. The majority of the population (Not HNI hunters) would pick out a spike out of a group of 6 does and a spike and kill it just because it is a buck....given the choice. Bucks don't stand a chance except to get smart or die, in terms of numbers. Id say your ratio is pretty good for free range deer. Some parts of Eastern NC, Eastern SC can get to around 1:10....lucky bucks when it comes time to rut.
