The amount of buck activity increases during the latter half of October until it reaches a pinnacle just before peak breeding begins. During this time only a small percentage of does are in heat but all the bucks are after them. In my experience, that scenario happens on, or just a few days after, November 7 nearly every year. Buck activity actually drops off during the peak of the rut because the majority of does are in heat and the mature bucks are holed up with them. Until most of the does are bred, buck activity remains hit-and-miss, as bucks finish with one doe and move to the next.
