People in Southeast Asia began harvesting chicken eggs for food by 1500 BCE. [2] Eggs of other birds, such as ducks and ostriches, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar.

The chicken (Gallus gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting.
Eggs are a "God-made product" and "an excellent source of protein," London said.. A regular egg has about 5 to 6 grams of protein — but it's also "packed with minerals" and "micronutrients" like ...
Fibromelanosis is also found in some other black or blue-skinned chicken breeds, such as the Silkie. [6] [7] The roosters weigh 2–2.5 kg (4.4–5.5 lb) and the hens 1.5–2 kg (3.3–4.4 lb). The hens lay tinted or cream-colored eggs, although they are poor setters and rarely hatch their own brood. Eggs weigh an average of 45 g (1.6 oz).
