I usually pass up about 20 small bucks a year (110" or less) and never pass a mature doe when offered an ethical shot. It has been proven time and time again that doing so will help produce a better age structure (among bucks) and keep your herd more in balance with the habitat. (generally speaking) Here in NY we have to harvest 60% of the doe population each year just to keep the herd stable. Unfortunatly we also harvest about 85 percent of our yearling bucks too.
