Help! Chick hatched with some yolk sac not absorbed

[Ewiens]

Hello. First time Hatcher here. I have 28 eggs on day 21. 8 have hatched and the last one is small, struggling and being pecked at by the other chicks in the incubator because there is some yolk sac not absorbed yet. What should I do? Or should I do nothing and let nature take it’s course? I have multiple other eggs pipped.

Put it in a cup until it absorbs the yolk.

It’s still in the incubator. Should I open it?
