A healthy herd will always consist of responsible Doe hunts. Also, the tighter the sex ratio, the more rut activity you'll be likely to see and it will assure more competition or breeding rights, thus only the most dominant mature animals will get the chance to fight their ways to breed the remaining Does. We have a pretty good control on the Doe population on and near our property and we will continue to shoot 4 or 5 Does for evey buck taken in the area. It would seem that in many areas, they need a harvest a lot heavier than that.
