The moon has a lot to do with deer. Espically breeding. A doe just like a womans cycle is 28 days... full moon every 28 days. Coincidence, I dont think so. The gestation period for a deer is 198 to 200 days average. Fawns are almost always born at the quater moon going into no moon. The reason for this is survival, preadators are not as active during the dark of the moon. You can look at the lunar cycle and go 198 days into the future and predict rut times pretty accurately
