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.

Why Me Why Not Her is a very moody dragon, always snapping at other dragons and getting into fights. But when alone she cries for the life that should have been hers, she's always wanted a mate, which she now can't have. She always wanted to be loved and desired but is now feared. She got her-self frozen so she could never bite a egg, to her that would be the last straw before she ended her life.
