In order for an egg to hatch into a chick, it must have been fertilized and either been incubated or had a hen lay on the eggs to grow the embryo from cells to a chick.

In this way, how do eggs become chicks?
Hens do not need a rooster to lay an egg; they do so (almost daily) on their own simply according to light patterns. However, if a rooster does mate with a hen, the eggs she produces are fertilized and, under the right incubation conditions, can bear chicks.
Secondly, how do farmers know if a chicken egg is fertilized?
