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.
