Egg: 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 found in almost all animals, from the eggs laid by birds, reptiles, fish, and platypus, and the eggs that are not laid by mammals and other animals. Eggs are an integral part of the reproduction cycle and are only found in females and hermaphrodites. Without eggs, most species would not be able to reproduce.
Bird eggs are most often consumed by humans, but some other animals may have their eggs consumed to fish and even reptiles, but for this journal we will concentrate on birds, primarily chickens. Birds, like other animals, lay their eggs after mating and care for them as needed until they hatch. They then raise their young, teach them everything they need to know, and then leave them to live their own lives.
But, sometimes an egg is not fertilized. Whe
