I would actually say w/ some certainty, as odd as it sounds, that some does are coming into heat now. I killed a pretty decent buck yesterday that was tending a doe, that was letting him get very close, like she was very close to letting him mount her, I cant be sure but she was defiantly behaving more like a nov 12th doe than a late oct. doe. I think there are probably a few does in every herd that are coming into estrus early for some reason and driving all the bucks crazy. Ive seen it in several different spots, and so have my buds. Like I said, get out there!
