Eggs need to breathe just like animals do!

Despite their solid appearance, egg shells have thousands of tiny pores
that allow moisture to leave the egg and oxygen to replace it. This
meets the needs of the growing chick perfectly - the evaporating
moisture makes more room for the growing chick while drawing in the

to incubate, it will absorb about 8 pints of oxygen and release about 7
pints of carbon dioxide and about 18 pints of water vapour.
