In 2019, the worldwide production volume of chicken eggs exceeded 82.17 million metric tons.

A 2010 USDA study determined there were no significant differences of macronutrients (carbohydrates, fat and protein) in various chicken eggs; when compared to cage-raised chickens, pasture-raised free-range hens, which forage for their own food, produce eggs that are relatively enriched in omega-3 fatty acids; chicken eggs that are especially high in omega-3 fatty acids are produced by feeding hens a diet containing polyunsaturated fats from sources such as fish oil, chia seeds, or flaxseeds.
