An alternative approach to learning about the rut in your area is to collect the ages of fetuses from harvested and road-killed does. The fetus age can be used to determine dates of conception. We've been doing this in MD, and find that breeding occurs over a period of several weeks, with the average date of peak breeding (peak rut) around 15 Nov.
Here is a plot for an article I wrote on the MD rut with data from does harvested in So MD over a number of years:
Not too hard to pick out that early rut behavior can occur in late Sept, and that there is a weak "second rut" in Dec. This past year, the MD QDMA State Chapter collected data from several hundred harvested does, and their "rut results" were similar - average peak breeding occured around 15 Nov (Predictions that the 2008 rut would be delayed due to the moon phase last year were not evident in the data).
This type of data bypasses a lot of the bias inherent with collecting observations of rutting behavior.
Good luck with your endeavor.
