biomedicalephemera:

Embryo of Chick in Shell
Shell removed and amniotic sac dessicated after 19 days incubation. Note the air sac on the left of the egg; without that, the chick would suffocate. The in the air sac oxygen is replenished through micropores in the shell. These micropores are also why if you have a particularly smelly fish, for example, in the same refrigerator as your eggs, the eggs will taste like fish even long after the fish has been removed.
