An '''egg''' is a reproductive capsule produced by many animals to reproduce. Fertilized eggs contain [[embryo]]s which develop into whichever [[animal]] laid it. Some animals have eggs which are only visible at a [[cell]]ular level, like humans for example. Usually the egg contains all the [[nutrient]]s the developing animal needs, but mammals some develop within their mothers (such as mammals), almost eliminating the need for eggs. Most eggs are considered tasty, such as [[chicken]] eggs, but they tend to [[Rotting|go bad]] after a short amount of time unless kept [[cold]]. However, eggs provide excellent sources of nutrition because of the nutrients they contain. | An '''egg''' is a reproductive capsule produced by many animals to reproduce.
