Might be the odd doe that was bred in early October that could have a fawn drop around now, but the main rut in the first 2 weeks of November lines up with a gestation period ending around the first week of June which is when the majority are born. From what I understand, some of the smaller fawns seen in the rifle hunt can be a result of young does not getting bred or going into heat for the first time in early December, resulting in a late June or early July birth. This could happen for a variety of reasons including doe age, maybe a buck shooting blanks, or a lack of bucks in an area with a large doe population.
