How long is the estrous cycle of a whitetail doe?

A deer's estrous cycle happens around the second week after the autumnal equinox, which is a fancy way of saying two weeks after the start of the fall season, or Autumn. Usually around the 2nd to 3rd week of October, this cycle will usually begin, and last through a month to 6 weeks. The reason I say six weeks, is because there are some deer out there that have a later blooming cycle. Altogether, this is the Rut season, and you can use the moon phases, and estrous cycle to tune in when you need to be in the woods for your best chances. During this time, the deer set off scents to one another to let each other know they are ready for some action, and really the only time during the season when deer that are not baited by feeders are at a disadvantage in the woods, because they can be manipulated into searching human made areas of interest. All in all, you can bet on a deer's cycle lasting around 4-6 weeks, and when it happens every year. It's just something in nature that sets them off. Hope that helps, but there are several articles and web sites devoted to this stuff, so if you can find any more truth to this, or a better way of stating it, let me know.
