There are several good reasons to have a commitment to shooting does, both old and young. First, a matriarch doe runs off her male offspring while letting the females join the herd. If you want your young bucks heading to someone else's hunting grounds, let her walk. Second, with less mature females on land with the same overall carrying capacity, birth rates will rapidly change from singles and twins to twins and triplets. The more multiple births, the greater the chance of a buck being born. Third, taking both mature and young does keeps the age spread consistently wide, which means that your hunting grounds have does that will go into estrus at different times. That means a longer rut period (or multiple rut periods if you prefer to label it that way) for your hunting pleasure. Finally, fewer does means more buck movement and competition with other bucks for the remaining does. Greater likelihood of seeing one plus generally higher success at rattling and grunting. Just my thoughts.

Glad to talk to all of you, but I'd rather be sitting in a tree stand on a cool morning trying not to move so that the bruiser buck directly below me doesn't figure out that I am watching him!
