Chicken and poultry are categorized into three general types: those used for laying eggs, those used for meat production, and dual-purpose breeds used for both. Chickens are distinguished by physical traits such as size, plumage colour, comb type, skin colour, number of toes, amount of feathering, egg colour, and place of origin. There are hundreds of chicken breeds, including bantams, which are miniature versions of larger breeds, and hybrids, which are crosses of two breeds. Chickens are frequently bred according to predetermined breed standards set by governing organizations, such as the British Poultry Standard.

Chicken meat and eggs became mass-produced in the early 20th century
Chicken is one of the most common types of poultry, with hundreds of distinguishable breeds that have been developed over thousands of years. Chickens are generally divided into three categories: those used for laying eggs, those used for meat production, and dual-purpose breeds.
The mass production of chicken meat and eggs began to take off in the early 20th century, with a few entrepreneurs selling young chickens for meat during the summer. However, year-round production was initially limited by a lack of understanding of the importance of vitamin D and the photoperiod in chicken production. The development of the "broiler"—a chicken raised specifically for its meat—changed this, with broiler production taking off in various locations across the United States.
The broiler industry experienced an economic boom, and by 1952, specially bred meat chickens surpassed farm chickens as the primary source of chicken meat in the United States. This was driven by "vertical integration," with single companies involved in every stage of production, processing, and marketing. The industry also benefited from advancements in science and technology, such as the use of antibiotics to increase chicken weight, and new pharmaceutical, biological, and production technologies.
By the mid-1960s, 90% of broilers produced came from integrated operations, and chicken meat and eggs had become mass-produced. The average American's consumption of chicken and eggs increased significantly during this time, with chicken becoming a staple food. By 1964, Americans were consuming over half a pound of chicken per week, up to 25-30 pounds per year. This trend has continued, with Americans now consuming an estimated two pounds of chicken per person per week, or roughly 100 pounds per year.
The mass production and consumption of chicken meat and eggs have transformed the food industry, with chicken becoming the number one meat in the United States. Slick marketing and advances in food processing have made chicken a mainstay of processed food products heavily marketed to consumers.

Chickens are categorised by primary use: egg-laying, meat-producing, or dual-purpose
Egg-laying chickens
Egg-laying chickens, also known as laying breeds, are selected and used primarily for egg production. These are mostly lightweight birds whose hens do not go broody often. Popular breeds include the White Leghorn, Red Sex Link, and Black Sex Link. A healthy hen will lay eggs for several years, starting at approximately 16–20 weeks of age. At 14 months, they will begin to molt and will not lay any eggs during this period. After molting, they will lay larger but fewer eggs per year.
Meat-producing chickens
Meat-producing chickens, also known as broilers, fryers, or roasters, are bred specifically for their meat. They are broad-breasted and larger than egg-laying breeds. They grow and feather rapidly and will weigh five pounds or more at eight weeks. Broilers and fryers are typically butchered at 3.5 to 5 pounds, while roasters are butchered at 6 to 8 pounds.
Dual-purpose chickens
Dual-purpose chicken breeds are used for both meat production and egg-laying. They are the classic backyard chicken, known for their hardiness and self-reliance. Most lay large brown-shelled eggs. Examples of dual-purpose breeds include the Rhode Island Red and New Hampshire breeds.
It is worth noting that chickens can also be categorised for ornamental purposes or as general agricultural birds. Additionally, while chickens are the most common type of poultry consumed worldwide, other poultry birds include guineas, geese, pigeons, and turkeys.

Chickens are also categorised by physical traits such as size, plumage colour, and comb type
Chickens are categorised by their physical traits, such as size, plumage colour, and comb type. There are hundreds of chicken breeds, which have been selectively bred to emphasise certain traits. Chickens are also categorised by their primary use, whether for eggs, meat, or ornamental purposes, with some breeds considered dual-purpose.
The size of a chicken is a distinguishing feature, with some breeds being larger than others. For example, meat-producing chickens tend to be broader breasted and larger than laying breeds. Roosters, or male chickens, are generally larger than hens, or female chickens.
Plumage colour, or the colour of a chicken's feathers, is another physical trait used to categorise chickens. Chickens can have a variety of feather colours, including black, white, and red. The colour of a chicken's plumage can also give an indication of its breed and primary use. For example, the Black Sex Link breed is primarily used for egg-laying, while the White Leghorn breed is also known for its egg-laying capacity.
Comb type is another physical characteristic that distinguishes chicken breeds. The comb is the fleshy growth on the top of a chicken's head, and there are several types of combs, including single combs, rose combs, and pea combs. Different breeds of chickens may have different comb types.
In addition to these physical traits, other characteristics such as skin colour, number of toes, amount of feathering, egg colour, and place of origin can also be used to categorise chicken breeds. These traits are the result of selective breeding practices and geographical isolation, which have created distinct regional types of chickens with unique physical and behavioural characteristics.
While chickens are primarily categorised by their physical traits and primary use, it's worth noting that cooking methods can also vary depending on the type of chicken. For example, young and tender chickens are suitable for various cooking methods, while older birds are better suited for braising or stewing. Different cuts of chicken, such as fryers and roasters, also have specific cooking methods that enhance their flavour and texture.

Roosters have been used for fighting, breeding, and meat production
Chickens and poultry encompass a diverse range of breeds, encompassing layers, meat producers, and dual-purpose varieties. Roosters, the male counterparts of hens, have historically been utilised for fighting, breeding, and, to a lesser extent, meat production.
Roosters have been employed in the ancient blood sport of cockfighting, where they are pitted against each other in battles to the death. This practice, with a history spanning back to 517 BC in China, was also prevalent in the Indus Valley, Israelite Iron Age sites, and various other regions. The sport involves breeding roosters for increased stamina, strength, and aggression towards other males. While cockfighting is now illegal in many countries, it still persists in certain areas, such as rural Pakistan, Haiti, and specific regions of France.
In the context of breeding, roosters play a vital role in protecting their flocks and exhibiting respect towards humans. When selecting a rooster for breeding, traits such as temperament, aggression, physical features, and conformity to standards like the American Standard of Perfection are carefully considered. It is recommended to choose from several options and retain multiple roosters to ensure protection and account for potential sterility or loss to predators.
While rooster meat is not commonly consumed in Western cultures, it is a staple in certain global cuisines, such as France's Coq au Vin and Spain's Arroz con Gallo. The toughness and gaminess of rooster meat, resulting from their denser muscle structure, contribute to their less prominent position in the meat industry compared to the milder and more tender meat of hens. However, incorporating roosters into our diets could offer economic and environmental benefits, promoting sustainability and diversifying the poultry market.
In conclusion, roosters have played a multifaceted role in human societies, serving as combatants in cockfighting, protectors and breeders in flocks, and a less conventional source of meat. Their involvement in these diverse realms has shaped cultural perceptions and practices surrounding these birds.

Poultry is commonly used in marinating due to its neutral flavour
Poultry is a food category that includes birds like chickens, turkeys, geese, ducks, and pheasants. Chickens, the most common type of poultry, can be categorized into three groups: those used for laying eggs, those used for meat production, and dual-purpose breeds.
Poultry is commonly used in marinating due to its ability to absorb flavours. Marinating is the process of soaking meat in a seasoned liquid or marinade before cooking. While it was previously believed that marinating chicken added moisture, tenderness, and flavour, recent studies have shown that the marinade does not penetrate beyond the surface of the meat. However, marinating can still enhance the flavour of poultry by adding flavour to the surface of the meat.
The process of marinating poultry involves using a blend of ingredients such as salt, acid (like vinegar or citrus juice), oil, and sweeteners. Salt is particularly effective in enhancing the natural flavours of poultry by dissolving proteins and reducing moisture loss during cooking, resulting in juicier and more tender meat. Additionally, the acid in the marinade can weaken the meat's tissue on the surface, although it should be used sparingly and for a limited time to avoid toughening the meat.
Poultry can be marinated for up to two days in the refrigerator, allowing ample time for the meat to absorb the flavours. It is important to follow recipes and recommendations to avoid over-marinating, as very acidic marinades can toughen the meat. Marinades can also be used on cooked poultry through a technique called "escabeche" or reverse marinating, where the meat is cut into smaller pieces while still warm and then soaked in an acidic marinade for 15 to 60 minutes.
Overall, while marinating poultry may not add moisture or tenderness, it is effective in enhancing the flavour of the meat by adding flavourful ingredients to the surface.
