Did this chick hatch prematurely?

[PNWhens]

Had an okay hatch rate, but one of them never moved after it’s initial pip and I have a feeling it was unable to breath and died. But when I examed the chick, it looks to be underdeveloped. There is a whole ball on the bottom of its stomach

Apologies for the graphic image

Looks both underdeveloped and something looks wrong.
