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.

∙ 11y agoEggs are living and need oxygen for respiration , which is diffused in through pores of shell .

∙ 12y agoAn eggshell has pores to allow for the exchange of oxygen needed by the embryo.
From the shell thickness and pore shape, the identity of the bird may often be inferred.

The Egg needs to be porous because inside the bird is living and needs oxygen to survive.

What types of eggs do reptiles lay?
Reptile eggs are soft-shelled - as opposed to the calcified shell of a birds egg.
Why is a shell not forming around a hen's egg?
You might need to supplement your chickens with oyster shell. I have one chicken I keep separate from the others I have to supplement because I give her treats. she needs the shell to help digest and to form the shell on egg.
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.
What is a leathery shell?
A leathery shell is a shell that is flexible rather than solid like the shell of a bird egg. A snake's egg has a shell that is flexible, as does a turtle's egg.
The shell of a birds egg is porus this means it has microscopic holes in it why does it need to be porus?
So the embryo can breathe!!
What is the outside covering of a birds egg?
It is known as the shell. The shell is composed of calcium carbonate.
What is the film around the shell of an unprocessed egg?
It is called "bloom" This is secreted by the hen just as the egg comes out of the vent and helps protect the porous egg from bacterial introduction.
Why does an egg float in a beaker of water?
Eggs are porous. The older the egg the more air contained within the egg shell. As the albumen inside the egg dries out with age, it is replaced by air. Fresh eggs will not float.
How do baby chickens breathe inside it's shell?
The egg is formed around the chick inside the mother bird after conception.

Why rotten eggs float in water?
As the egg decomposes, the mass of the egg is reduced. This is because the egg shell is porous and water vapor and gases can escape over time, reducing the mass of the egg. If the mass of the egg is less than the mass of the volume of water displaced by the egg, it will float.
Why does egg of birds which is a single cell so big that it can be seen through unaided eyes?
The shell of an egg needs to be big enough to keep the chick inside until it is ready to hatch. The "Egg" you see is not a single cell. The cells are inside the shell you see. These single cells are like normal cells, you need microscopes to see them.
What does the membrane that line the egg shell do?
The shell is calcite - calcium carbonate - on a protein framework. It is porous to allow gas exchange and loss of water during incubation. Colour is added late in the development of the egg so is only within the very surface layer of the egg.
