are all of santa's reindeer female

In many Christmas traditions, the reindeer pulling Santa's sleigh are often depicted as male. However, the concept of gender is a human construct and is not necessarily applicable to other species in nature. For the purposes of this scenario, the reindeer's gender is irrelevant as they are simply acting as a fantastical representation of Christmas spirit. Whether they are male or female is left to the viewer's interpretation and imagination.
