The pyramids or Egyptian hatcheries—which is more impressive?

 The Pyramids Are Not Considered More Amazing Than The Egyptian Egg Ovens

In rural Egypt, a hatching technique created more than 2,000 years ago is still in use.

Farmers still using the same methods that were created two thousand years ago.

Ancient Greeks were greatly influenced by Egypt's mathematics, papyrus-making, painting, and egg-hatching, among other facets of their civilization. The historian Diodorus Siculus described Egyptian egg-hatching as miraculous 200 years after Aristotle first made note of it, claiming that eggs "are produced spontaneously in the ground, by being buried in dung heaps" in Egypt. He penned the following in his forty-book historical anthology, Library of History

The most astounding fact is that the guys [in Egypt] in charge of chickens and geese rear them by hand, in untold numbers, using a skill unique to them, in addition to raising them in the natural way known to all people due to their extraordinary application to such matters.

The Egyptian egg incubators were a clever system of mud ovens created to mimic the conditions under a broody hen, to which Aristotle and Diodorus were alluding.

When Aristotle and Diodorus spoke about Egyptian egg incubators, they were talking to a clever system of mud ovens created to mimic the conditions inside a broody hen. An egg oven may hatch as many as 4,500 fertilised eggs in two to three weeks with a lot of heat, moisture, and regular egg-turning; this amount has long impressed visitors from other countries. The amazing constructions were frequently cited by Western tourists in their writings about Egypt. René Antoine Ferchault de Réaumur, a French entomologist, visited an egg incubator in 1750 and said, "Egypt ought to be prouder of these than her pyramids."
