"if does get bred in March up here they wont drop until September or later. Those fawns wouldn't stand a chance."
Not exactly true, depends on the severity of the winter weather, available food sources, etc., etc... Although uncommon, have seen pix of NORTHERN spotted fawn photos in winter snow as far north as Minnesota, Upstate NY, Ohio, and I think I may even have a winter photo of a spotted fawn in Canada... Mild El Nino winters such as this year, there may be good chance of some surviving...
