Help?

I am hatching Call ducklings in my classroom with my students. Yesterday was day 26 and all 6 eggs were rocking and 3 had began pipping. This morning one duckling was completely hatched when I arrived at 6:30 and another hatched around 11:00. The rest of the eggs have shown no more signs of movement or progression. I am using a mini Brinsea advance so it is pretty good classroom incubator and previously have had a 100% success hatch rate with calls. Suggestions? Opinions? Thank you.

It's still early and they can sleep for a day prior to hatching out. They turn in the shell (the egg rocking) and internally pip for air. You can hear them chirp or they will sleep for some time before externally pipping and zipping. It's a lot of energy to hatch and some take it in stages. Your actual hatch date is tomorrow.

They can get quiet before a hatch don't start panicking until they are a few days late.
