Hatching Duckling, Putrid Smell

[Ponytales1976]

So I have Call Ducks hatching right now. One of them smells like it is dead and rotting, but it's a live duckling. What do I do?

 

[GitaBooks]

Ducklings can injure themselves during the hatching, such as tear their yolk sac or umbilical cord. They may be deformed, have poor genetics, or have improper incubation conditions.

Is it weaker than the others?
Does its "belly button" look swollen, leaking, or infected?
Is it deformed in any way?
Are there any injuries on it?
Was its egg dirty before incubation or during at any time?

I hope it is fine and that there is nothing to worry about. Best of luck!

It wasn't totally hatched yet, "it" passed away last night before it finished hatching

I'm really sorry.
