- The structure of an egg An egg is a reproductive cell from which a new organism develops. This will occur only if the egg has been united with a male sperm cell (fertilized). A chick will hatch from a fertile egg if the egg is incubated at 100.5 degrees F for 21 days. You can tell if an egg is fertile by candling and identifying a mass or small spot in the egg. The egg will appear incandescent, and the mass will be dark.
