Take it from somebody that has 1165 acres of mainly native deer under high fence, bucks die at a super high rate due to fighting and getting run down. We try to keep our doe population at around 125 and there are no more than eight bucks a year taken. In a perfect world you would think you should have at least 60 bucks having a birthday every year but that is not the case. We may have five a year that make it to five years old.
