What is an egg?

Answer 1

The official definition for the word egg is "an oval or round object laid by a female bird, reptile, fish, or invertebrate, usually containing a developing embryo. The eggs of birds are enclosed in a chalky shell, while those of reptiles are in a leathery membrane."
Eggs are the pre-stage of birds, reptiles, and assorted other animals. An embryo, rather than form inside the parent organism, exits it's mother in a case, either hard or soft, and devolpes inside of this enclosure until they are fully formed. They then emerge and are almost immediatley ready to explore the world.

Of course eggs do not always hatch, if the eggs are not fertile, the embryo never forms, many eggs must be incubated, and, if they are not the unborn young will die. Eggs can also be broken or eaten. hi there
