Could it be that you have too many does, and not much pressure for the bucks to fight over mating rights? I read somewhere that in my area, we have way too many does and because of this there is less competition for mating partners, so bucks don't display as much competitive behavior, in areas where the buck/doe ratio is closer to 1:1, then the rubbing and scraping activity is much more pronounced, and the length of peak rut is more compact. Our peak rut is late and lasts a long time. We typically see small, spotted fawns during Oct/Nov and the rut lasts into Feb after season ends. I am by no means an expert, but I read a lot. Check out the Mississippi State web site, they do a lot of deer research and publish their findings on the web.
