Need advice about poor condition hatchling

[Cheesenugget]

Thanks for all the advice, but he passed sunday (5/31). I think the pet store waited too long or he had something serious from birth.

He never perked up even with increased temp and light. By Saturday night he wouldn't move at all on his own, and didn't really open his eyes even when touched or hearing noises.

At least you tried. A good breeder or pet store would never stock such a small baby for sale. They can't compete with their bigger siblings, who will continue to hog up all the temps and food until the small ones perish. Not only that, some are born not to live that long. It is nature, and not uncommon in beardie babies, especially if the mom was bred constantly and not properly cared for.
