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.

Why Does a egg shell have to be semipermeable?
So the growing chick inside gets air to breathe.
Who invented how a chick breathes inside its shell?
God.
What is what is the function of the air space in egg?
The developing chick inside the egg needs air once its lungs develop, this reserve air sac allows the chick to breathe and gives them room to maneuver when it is time to peep (break out of the shell).

What does a turtle use it's shell for?
The turtles shell protects itself and hides inside its shell when in danger or when they are scared. The shell helps the turtle breathe. The turtles shell is another way to breathe for them.
How does a chick get inside an egg?
There will be kind of pocket in the egg which contains enough oxygen for the chick to breathe in the egg for 21 days.
How do baby chickens breathe inside it's shell?
The egg is formed around the chick inside the mother bird after conception.
How does the chick nourish it self inside the egg shell?
the chick develops on the edge of the egg yolk (the yellow part) as it grows, the chick absorbs the nutrients from the yolk into it's body as food.
How does a chick get oxygen while developing inside the egg?
Like all embryos, a chicken in the egg does not require air to breathe until such time (approximately day 19) when their lungs develop enough to use the small amount they need. When it is first laid, the egg is full of yolk and albumen. At that time there is no air space as it is not required. The egg shell is porous. Moisture is lost through the shell over time and the moisture is replaced by air. When we breed chickens on the farm, we keep the small end of the egg up so the air collects above the developing chick. This air will be used by the fully formed chick inside the egg while it "PIPS" its way out of the shell at day 21.
Do the shell get bigger when the chick in side does?
No, an egg shell will not expand as the chick grows, once the chick has 'outgrown' its shell it starts to chip a small hole in the shell, then begins to break out into its new world.
Why does a shell of a birds egg need to be porous?
When the baby chicks are developing in the egg shell, they need to breathe. The pores in the egg shell allows an exchange of good air with the bad air. A side effect to this. The pores allow moisture to escape from inside of the egg.
How does the chick get out of the egg?
An unhatched hick develops a hard 'shell tooth' by the time it is ready to hatch and uses it to tap against the inside of the shell until it makes a small hole. The chick then pecks at the edges of the hole to enlarge it until the opening is large enough for it to escape from the shell.
