Just a question, have the does changed food sources by then to a preferred source that is not on your property? If the Does move so do the bucks. That and the bulk of the breeding is done, so the bucks main focus is putting weight back on. But my bet is that if they catch a wiff of a doe coming into heat in December that focus changes on a dime. I used to hunt in Gratiot county Ag country. There was a huge doe population on my Aunt's farm. I was lucky enough to experience the second or late rut several times. All it took was for one doe to come into heat, and there were bucks everywhere it seemed. That being said any buck left by Thanksgiving has run the gauntlet for months by then. Seeing a buck by then or into December was tough unless there was a hot doe around. Just my observations on that property.
