Unabsorbed yolk? Hernia?

Can someone tell me what this is? The chick hatched yesterday and I didn’t even notice it until now. He/she is up and walking & chirping, seems strong but I’m worried she’ll get pecked apart by the other chicks. What do I do?

It looks to be right below the vent?
Hard to tell for sure from the pic.
The umbilicus is farther down the body.

When the chick stands/sits normally it isn’t noticeable, it’s underneath her body.
