That may be why there is a delay...
my big eggs developed but failed to hatch. The late hatchers may also have trouble getting out, in which case you may need to help:

Are you sure the day is correct?
Most of them should have hatched already, but you can leave them in there for another 24 hours; tapping and chirping is a good sign, but not response isn't bad; they may be resting
If they haven't made any more progress after 24 hours, then i'd start to get worried 😊
