Duck egg chirping at day 24

[Runer]

Cool! Do you have Runner ducks?

No, this is my first experience with birds.

Now another egg cracked. Still no actual holes, is this normal?

Like this? It sounds normal. There are never holes. If there are there's a problem.

No, this is my first experience with birds.

Oh okay, I have Indian Runner duck so just wondering

So the second one with a crack made a hole and is chirping out loud, but nothing from the first one. Should I help, it's been over 12 hours.
