This hatchling appears to be... dead?

Perhaps not. It seems to be active during the night.

Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it typically marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.

Vampiricus Algidus wanted to be a grown-up vampire. But because he bit an Ice egg, he froze on the spot. The other dragons—even the vampires—laugh at him and say it serves him right—and some day, he growls to himself, he will get them all back. Meanwhile he whines to himself about the unfairness of life.
