Answer:
Chicken eggs have a porous shell and will lose moisture during the incubation. They have a air chamber within the shell and will get larger as the chick develops. Sorry for the interruption, my router disconnected. On day 19 the chick will thrust it's beak into the air chamber and breathe that air till it hatches.

The lungs of the developing chick are not formed or functioning until day 19 of incubation. The use of the albumen within the shell for the embryo allows room for air to gather as absorbed by the porous shell. That small amount of air is enough for the chick to use until the egg tooth opens the shell. This is one reason a double yolk egg fails to fully develop.

The egg is porous, meaning it has very very small holes where the chick can breathe.

If u look they have an air sack on the top of the egg
