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.

Dj Vamp egg was brought into this world by a Green dragon and a Gold dragon, but he is neither. He is a vampire dragon bitten by Blood Death, his mother in his mind. As all Vampire dragons, Dj lives for the night and hide from the light. He doesn't mind that he isn't as strong as Blood and can't go anywhere in the sunlight, or it will give him a deadly burn. He never saw what the land look like with the sun shining over it and never will, but he is okay with that. He's happy with the moon light. He like making music, but he can't sing at all. He dreams to write songs for a human singers one day. The other hatchlings sometimes act weird around him because he lives off only blood unlike any of them. Dj favorite thing to make Blood Death do is tell him the story of how she saved his life in a way..
