Are Dogs the Most Common Domesticated Animal?

If you thought yes, you’re way off. The most common domesticated animal on earth is, by a long shot, the chicken.

Although this familiar bird is the descendant of a jungle fowl from Asia that wasn’t domesticated until about 1500 B.C., there are now some four billion chickens on earth, about the same number as there are people!

The United States has almost 400 million chickens, but the nation with the largest chicken population is the Soviet Union, with more than 560 million.

The chickens of the world lay about 400 billion eggs each year!
