You know it's cold when you can see the reindeer's breath.
Bottom of a reindeer's hooves. Sorry, it's a bit blurry, but that's a hard shot to get.
Both sexes of reindeer have antlers. Males usually lose theirs in December, females keep them all winter long. That means Santa's reindeer, always depicted with antlers, are all female.
This deer is eating shredded beet pulp, a high-energy alternative to alfalfa. We feed our sheep mostly alfalfa, but they get a ration of beet pulp as well. The orange disc is a Nilla Wafer; reindeer are crazy about them.
