The yellow and grey area for example is likely just variance in the sampling occurring between the Jan and Nov doe herds with I-59 in the middle…..Keep in mind that the state’s map is not a complete true picture but just the one they are able to make from the individual sites that have been surveyed…..They are reporting the “average” conception date. If you average Jan and Nov you get a date in December……You also get some possible second estrous cycle does from the Nov area which trick some folks into thinking there are three ruts....These "variance areas" could potentially see a hodge podge of action
