Chirping and scratching in egg but no internal pip

[Ollie00]

Hey all!
So I’m on day 22 hatching chick eggs. I had one born 20 hours ago all good.
His brother egg has no external pip, no internal pip that I can see but I can hear chirping and scratching from inside the egg.

What should I do? I wonder if he has enough oxygen without taping the air cell??

Did this chick hatch?

Did this chick hatch?

Yes! I had to intervene but he’s doing great now! I posted another thread about it.
