beak not in air cell

[Aelrift]

Icubtaing muscovy. I can see the beak but it's not in the air cell. Is it normal? There is about a week left of incubation, what should I do?

You don't need to do anything.
When it is closer to hatching time the duck get the beak into the air cell...it's called an internal pip.
