Egg not hatching after pipping for more than 2 days

[MGG]

Only the egg that pipped earliest hatched but the second should be soon! I doubt the third egg will hatch because they have developed very late (still hasn't shadowed but is moving). Thank you!

Have you checked the internal incubator temp with a calibrated thermometer? That brand of incubator is notorious for being difficult. The digital read in any incubator is usually wrong, so don't trust it.
