I’m not 100% sure of the accuracy of this but it certainly sounds plausible. Perhaps Santa could confirm this?
According to the Alaskan Dept. of Fish and Game, while both male and female reindeer grow antlers in the summer each year, the male antlers drop their antlers at the beginning of winter, usually late November to mid-December. Female reindeer retain their antlers until after they give birth in the spring.
Therefore, according to EVERY historical rendition depicting Santa’s reindeer, EVERY single one of them from Rudolph to Blitzen, had to be a girl.
We should have known… only women would be able to drag a (ahem – sorry Santa) rather largish man in a red velvet suit all around the world in one night and not get lost!
