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.

The Prince of Gore is the first vampire son of the wicked Bloodscale and just as ferocious. While most vampire hatchlings drink blood leftover from adults, the Prince insists on hunting with them (whenever they manage to escape). He has been known for killing dragons much larger than he is.
