Not all babies make it out, and there are all kinds of reasons why. There is not much you can do for the baby until it has broken into the internal air cell, because it is not ready to breathe yet and will bleed to death if you open the membrane. However, it's also possible it's just really slow getting going because of the unusual incubation circumstances. It may have been sitting in a cool spot, and that will slow it down significantly. For now, just keep it warm and candle it from time to time. It may surprise you. Good luck to the little one!
