The gestation period for whitetail deer is supposed to be 200-205 days. The trail cam pics that I have are around the 26th of August that would put the doe being bred around the end of the first week of Feburary. I don't believe that the light or even the weather plays a big of a part as does the variation of breed of deer, such as where they were imported from. There are places in Calhoun county where the rut occurs around November. What i am worried about is the mortality rate of the fawns that die due to doe mother being harvested while the fawn is still in an early stage.
