I have a question, I have a chick who started pipping and zipping yesterday afternoon/ early evening, and had stopped. no new progress, I am not even seeing movement from inside the egg. Should I be concerned or is this common? I know the rule is it can take up to 48 hours from pip to hatch, but what about when they have started to zip, how long before i get very worried?
Zipping takes up to 90 minutes
