and anyone else involved in this discussion. :)
Santa’s reindeer are magical. They can fly. Ergo, males keep their antlers till after Christmas, which helps with pulling Santa’s sleigh and navigation.
Going by their names, possibly Prancer and Vixen are females, but most are males.

According to Cheech Marin, Santa’s reindeer were given magic dust, which gave them the ability to fly.
