Unabsorbed yolk sac or something else ??

Is there anything I can do for this chick? Eager beaver came out like a wrecking ball. Very alert and seems strong, thankful it fell on its back so I could snap a couple pics.

Yes that looks like unabsorbed yolk sac. Can you pop the chick in a small cup inside the incubator so it can finish absorbing the yolk?
