@Emily Colwell I’d really advise reading through the Guide to Assisted Hatching that I linked above, and at the very least make a safety hole so baby can breathe properly.
I had to google the thread and copy the link for it lol. I’m not sure how you’d do it in the app

Sorry you didn’t get a response yesterday.
– Has the baby pipped externally since?
– If not, could you get a picture of you candling from the air cell?
If you can’t tell if there’s an internal pip from candling, you can also try holding the egg up to your ear and tapping on the shell...
