Help!!! Duck hatched attached to umbilical cord

[Lovem all]

I love their little makings, and they have such cool unique names

This is my first time hatching ducks and I really need a hand... she hatched yet she’s clearly still attached..
I’m guessing she’s premature... please help... she’s loud but sleepy

My duckling has the same thing but idk if it’s still absorbing or just the cord to the membrain
