Chick started zipping then stopped

[LaserDaiser]

Hello! I have 12 eggs in my incubator. It’s day 20 today. 2 pipped yesterday on day 19 and one hatched yesterday night. The other one that pipped started zipping in the wee hrs of the morning (day 20) I did not see this happening as I was asleep. Woke up to find it 1/4 zipped.
It’s now 1 pm and I have seen no more attempts from the chick to get out. I see movement so he/she is still alive. I’m wondering if I should help, but I’m worried about opening the incubator for fear of shrink wrapping any of the remaining 10 eggs. What should I do?

I personally wouldn't assist yet unless I noticed the membrane was super sticky/shrink wrapping. It's still early on and it might be finishing up absorbing the yolk sac.

Ok it hatched. But it might have an umbilical hernia??

I'm not as familiar with those but did see an old thread where a duck had a similar one and it healed up ok!

He/she is very active and vocal. Hopefully it will pull through
