So, first pic: the eggs, which has been pipped, and some sections of the shell have broken away. The inmate has made a little tear in the membrane. The other items you can see in there are hatched chicks, and in the left lower part of the incubator, that square thing is the hygrometer.

One of the siblings has come by and is about to trip and fall over the new hatchling, and then fall asleep, delaying things a bit.
Almost out, after the sibling has staggered off somewhere else!
Finally the creature emerges, ready to eat Tokyo. Or some chick crumbles, anyway.
