I'm sorry for all the threads! My babies are starting to pip and I'm anxious lol. So I had an egg pip yesterday. She hasn't made any progress since the initial pip (18hours or so now)so carefully I took a chip of the shell back and she hasn't punctured the membrane but she has gone through her air cell. I'm still sitting on my hands but I'm getting nervous, I don't want her to suffocate.
EEK! it has been over a day since you posted.... hopefully everything worked out... but if it didn't, this is the best article to read about what is normal at hatch, and when you should help, and HOW to help safely: https://www.backyardchickens.com/a/step-by-step-guide-to-assisted-hatching
It did work out. She pipped and stayed in the same place with no progression for 22 hours. I was really getting worried! But she started up and within 2 hours she was born! I had 12 eggs and so far 10 have hatched! For shipped eggs that's pretty awesome!!!
Here they are I only have two Lavender orpington eggs left. Those were the only two that made it all of the way. Hopefully they pip soon!
