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.

McVampy is the pariah of the hatchlings at this particular cave. None of the other hatchlings quite trust her—they're rather afraid they'll wake up in the middle of the night with her gnawing on their ankle. Fortunately for them, she has a more sophisticated palate, and prefers delicacies such as quail, and duck. She's got a bit of a bad streak in her though, and often sneaks out of the cave at night to go wreak havoc with hatchlings from neighboring caves.
