According to the Alaska Dept. of Fish & Game, while both male & female reindeer grow antlers in the summer each year, male reindeer drop their antlers at the beginning of winter, usually late Nov to mid-Dec.

Female reindeer retain antlers till after they give birth in the spring.

Therefore, according to EVERY historical rendition depiction Santa's reindeer, EVERY single of them, from Rudolph to Blitzen, had to be a girl.

We should've known... Only women would be able to drag a fat-azz man in red velvet suit all around the world in one night & not get lost..

HAVE A MERRY CHRISTMAS & A HAPPY NEW YEAR
