I hatched out one of these blue Bellies about two weeks ago. Seeing it first hand it looks like it has some thing to to do maybe with the yoke sack and like most people are saying its prob an enzyme. There was no pigment on the skin its self. My baby was also a preme i have no clue if that had an effect on it at all. after the first shed the "blue" was almost totally faded and at this point it is totally gone. I will keep a close eye on this gecko and see if there is any long term health issues. there are more pictures on my facebook but here is one of them.
