Chickens are the most common domesticated bird in the world, with an estimated global population of over 20 billion. In the US, there are approximately 8.9 billion chickens, second only to China's 9.6 billion. The domestic chicken's ubiquity is largely due to its widespread use in the food industry for meat and egg production. In 2017, the US produced 106.7 billion eggs and 19.71 million metric tons of chicken meat in 2019. While chickens are the most common domesticated bird, the most abundant wild bird is the red-billed quelea, native to sub-Saharan Africa.

What You'll Learn

The US has the second-highest number of chickens in the world
The domestic chicken (Gallus gallus domesticus) is the most common bird in the world, with an estimated global population of over 20 billion. In 2023, it was estimated that there were around 24 billion chickens worldwide, up from 23.7 billion in 2018 and 14.38 billion in 2000. The United States is a major contributor to this number, with the second-highest population of chickens in the world at 8.9 billion. This large population is due to the bird's widespread use in the food industry, with chickens being predominantly bred for egg-laying and meat production. In 2017, the US produced 106.7 billion eggs and 19.71 million metric tons of meat in 2019.
The abundance of chickens in the US can be attributed to the country's high demand for poultry products. Chickens are a significant source of food for Americans, and the industrial production of chicken meat and eggs has become common since the 20th century. Chicken is now an important part of the American diet and cuisine. Additionally, the US has a large poultry industry that contributes to the country's economy. The industry involves various sectors, including breeding, farming, processing, and distribution. The US is also a major exporter of poultry products, supplying chicken meat and eggs to many countries worldwide.
While the US has the second-highest number of chickens globally, China leads the world in chicken production, with 9.6 billion chickens. This number is expected, given China's large population and cultural preference for chicken meat and eggs. China produced 529 billion eggs in 2017, significantly contributing to its chicken population.
It is worth noting that the red-billed quelea (Quelea quelea) is considered the most abundant wild bird species. Native to Sub-Saharan Africa, the red-billed quelea has a population of about 1.5 billion breeding birds. They are highly sociable and feed in large flocks, giving the impression of a rolling cloud. While attempts have been made to control their population, these methods have been largely unsuccessful.
In summary, the US has the second-highest number of chickens in the world, with 8.9 billion birds. This significant population is driven by the country's high demand for poultry products and the industrial production of chicken meat and eggs. The US poultry industry plays a crucial role in meeting domestic and global demands, contributing to the country's economy and culinary landscape.

Chickens are the most common bird in the world
The large-scale industrial production of chickens for food became more common in the 20th century, and now chicken is a significant part of almost all global cuisines. The global chicken population is also boosted by the fact that chickens are sociable birds that feed in flocks of millions. As birds at the back of the flock run out of food, they fly over the birds in front to reach a fresh feeding area, creating the impression of a rolling cloud.
While the chicken is the most common bird overall, the most abundant wild bird is the red-billed quelea (Quelea quelea). This sparrow-sized bird, native to Sub-Saharan Africa, has a population of about 1.5 billion. The red-billed quelea travels in large flocks, creating a spectacle that looks like a cloud overhead. Farmers in several African countries have attempted to lessen or eradicate the quelea population through lethal control methods, but these measures have been largely unsuccessful due to the nomadic nature of these birds.

Chickens are used for eggs and meat
Chickens are the most common domesticated bird in the world, with a global population of 24 billion as of 2023. They are primarily kept for their meat and eggs, with over 50 billion chickens produced annually for consumption. In the United States alone, more than 8 billion chickens are slaughtered each year for meat, and over 300 million are reared for egg production.
Chickens are a subspecies of the red junglefowl, native to Southeast Asia. They were first domesticated around 8,000 years ago and have since become a central component of global animal husbandry and agriculture. The widespread use of chickens as a source of food became more common after large-scale industrial production started in the 20th century. Today, chicken is an important part of almost all global cuisines.
Chickens are social animals that live in flocks and exhibit complex behaviours. They establish a "'pecking order'", where dominant individuals take priority for access to food and nesting sites. Hens will often try to lay their eggs in nests that already contain eggs and will move eggs from neighbouring nests into their own. Under natural conditions, most birds will "go broody", incubating their clutch of eggs until they hatch.
Specialised breeds of chickens have been developed for meat and egg production. A hen bred for laying can produce over 300 eggs per year. Dual-purpose breeds, such as the Rhode Island Red and Speckled Sussex, can also provide both meat and eggs. These breeds are efficient, requiring less feed and water than other breeds. However, it's important to note that roosters do not lay eggs, so they are primarily used for meat or to fertilize eggs.
In recent years, the Highly Pathogenic Avian Influenza (HPAI) outbreak has impacted chicken flocks and contributed to rising prices for poultry meat and eggs. Despite these challenges, chickens remain an important source of food and continue to be widely used for both egg production and meat.

The US's national bird is the Bald Eagle
Chickens are the most common domesticated birds in the world, with an estimated global population of 22.67 billion. In 2023, it was estimated that there were about 24 billion chickens worldwide, up from 23.7 billion in 2018 and 14.38 billion in 2000. China leads the way with 9.6 billion chickens, followed by the US with 8.9 billion. In the US, chickens are primarily used for egg-laying and meat production. In 2017, the country produced 106.7 billion eggs, and in 2019, it produced 19.71 million metric tons of meat.
While chickens are the most common domesticated birds, the most abundant wild bird is the red-billed quelea, a sparrow-sized bird in the weaver family with a population of about 1.5 billion. This bird is native to sub-Saharan Africa and can be found in tropical and subtropical areas with semi-arid climates, avoiding forests, deserts, and colder regions.
Now, while chickens may be the most common bird in the US in terms of population, when it comes to symbolism and cultural significance, the bald eagle takes the top spot as the national bird of the United States. The bald eagle is a large bird of prey found only in North America, making it a truly "all-American" species. It was adopted as the national emblem in 1782 and has been an important symbol of the country ever since. The bald eagle is also sacred in some Native American cultures, and its feathers play a central role in many religious and spiritual customs.
The bald eagle was chosen as the national emblem due to its long association with the country's history and its unique status as a species endemic to North America. The founders of the United States also drew inspiration from the Roman Republic, where eagle imagery was prominent. The bald eagle's comeback from near extinction to being removed from the federal endangered species list makes its story even more compelling and symbolic of American resilience.

The Mourning Dove is common in warmer parts of North America
The domestic chicken (Gallus gallus domesticus) is the most common bird in the world, with an estimated global population of 24 billion as of 2023. China leads chicken production with 9.6 billion, followed by the US with 8.9 billion.
However, the Mourning Dove (Zenaida macroura) is one of the most abundant and widespread birds in North America. It is sometimes called the "American mourning dove" to distinguish it from the mourning collared dove of Africa. The Mourning Dove is found in eastern and western North America, parts of Mexico, Central America, and some islands off the coast of Mexico. It occupies a wide variety of open and semi-open habitats, including urban areas, farms, prairies, grasslands, and lightly wooded areas. It avoids swamps and thick forests.
The Mourning Dove is a popular game bird, with more than 20 million birds (up to 70 million in some years) shot annually in the US. Its ability to sustain its population under hunting pressure is due to its prolific breeding; in warm areas, a single pair may raise up to six broods of two young each in a single year. The Mourning Dove is light grey and brown in colour and has an unusual whistling sound upon takeoff and landing. It is a strong flier, capable of speeds up to 88 km/h (55 mph).
Audubon's scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect the Mourning Dove's range. The Mourning Dove is well-adapted to man-altered habitats, and its numbers have likely increased with the increasing settlement of North America.
