URGENT! gosling didn't absorb the yolk or what?

[chickengr]

I have a gosling in the bator that hatched 24+ hours ago. it looked like it didn't absorb the yolk but that staff is pinkish and the little "hanging ball" is getting black (rotting?). is there anything I can do about it?

Do you have a picture?

sorry no pic.

I did some research and put some betadine on that thing. it seems that is the only thing I can do and wait.

might be umbilical hernia. whatever it is I hope it will get in. it was double size yesterday so I have almost 48 hours of hope.
