The World's Most Common Bird
Chickens are among the most domesticated animals on Earth, with a history of human partnership stretching back over 8,000 years. Originally descended from the red junglefowl of Southeast Asia, they were likely first kept for cockfighting and ceremonial purposes before their value as a food source became the dominant reason for raising them. Today there are estimated to be more chickens alive at any given moment than any other bird species — somewhere in the range of 25 to 30 billion worldwide.

A Bird Woven Into Culture
Chickens occupy a peculiar cultural space. They appear in idioms and proverbs across nearly every language and culture, often symbolizing cowardice, fertility, or domesticity. Yet they also carry deep religious and mythological significance in many traditions. In ancient Rome, the behavior of sacred chickens was used to divine military outcomes, and generals reportedly delayed or canceled battles based on whether the birds were eating enthusiastically.
Smarter Than You Think
Despite their reputation as simple farm animals, chickens are surprisingly intelligent and socially complex. They live in structured flocks with clear hierarchies — the origin of the phrase "pecking order" — and they communicate through a repertoire of over 30 distinct vocalizations. Hens have been observed demonstrating basic empathy toward their chicks, and studies have shown that chickens can perform rudimentary reasoning tasks, including understanding that an object still exists when it's hidden from view.
