Internal pip but no external pip.

So today is day 21 and there has been some wobbling and I can hear a few of the chicks cheeping. How long should it take from internal pip to external pip? Really don’t want them to run out of air I am hatching chicks over a blog with my preschool class as they would be missing out due to schools being shut. Really worried I don’t get any chicks, the pressure is on! How long would you leave them?? Thanks in advance. (I only know they have internally pipped from hearing them cheep, been in lockdown since day 18) Thanks in advance.

It can take around 24 hours from internal pip to external pip. Then it can take 12-24 hours, and sometimes a little longer, for the chicks to start unzipping. But you will find yourself checking on them every 5 minutes.

Ok so they should not suffocate! Usually they are on time when we incubate! The eggs also came via post so have saddled air sac and one was very porous, hoping they will be ok, even just one for the kids to see. Haha yep im in there every 5 mins cheeping at them
