Oh most definately they're absorbing yolk. I learned that the hard way. I looked in and saw one opening and closing it's beak and though o m g that chick's in distress and it's gonna die! So um...I helped it. Dumped it out of the egg and it still had yolk to absorb. The happy ending was that it did finish absorbing the yolk. I could have killed it though. If that yolk gets broke or the umbilical cord gets severed before it's done....it's done.
So I'll never do that again.
