Golden Egg

The Goose that Laid the Golden Eggs

"The Goose that Laid the Golden Eggs" is one of Aesop's Fables, numbered 87 in the Perry Index, a story that also has a number of Eastern analogues. Many other stories contain geese that lay golden eggs, though certain versions change them for hens or other birds that lay golden eggs. The tale has given rise to the idiom 'killing the goose that lays the golden eggs', which refers to the short-sighted destruction of a valuable resource, or to an unprofitable action motivated by greed.

Egg

An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell – a zygote. Within the vessel, an embryo is incubated until it has developed enough to survive on its own, at which point the animal hatches. Reproductive structures similar to the egg in other kingdoms are termed "spores", or in spermatophytes "seeds", or in gametophytes "egg cells".
