In 2 hours I will be on day 21. I have none hatched yet. I have one that I dropped and cracked on day 17. I put scotch tape over the pretty big crack I saw movement right before lockdown. I didn't remove the tape prior to lockdown. The crack wasn't over the air cell so I though it would be ok. Yesterday around 1pm I heard peeping from this same egg. I just heard peeping 2hrs ago but no pips yet. I have 9 eggs total in the bator (brinsea Eco) this is the only one I hear peeps from. My question is how long after I hear peeps should they externally pip? We are over 24 hours now.
