 Do chicks get air while in egg?

How does developing chicken get air to breathe, while inside an egg? To explore you need raw egg and food colorings.

. Boil an egg on a low flame. Observe a stream of air bubbles coming out of the broader end of the egg.

 [Don't confuse with bubbles of air dissolved in water; they also stick to the egg.]

. After boiling sufficiently, stop heating. Add some food coloring to the water.

After it cools, take out the egg and peel of its outer shell. Food cooler has entered the shell.

. There are two thin membranes, between the shell and the liquid of the egg. Just at the broader end, some air is present in between these membranes.

 The growing chicken breathes this air. If you carefully peel off a boiled egg, you can see these two membranes distinctly.

. Eggshell is porous, consisting of numerous tiny holes. When heated, air inside the egg expands and starts coming out of the pores.

 When allowed to cool, the pressure of air inside the egg decreases and colored water enters through the pores.

. The balanced of the oxygen and carbon dioxide is continuously maintained by the processes of the diffusion and osmosis through the pores in the eggshell.
