What You'll Learn

Young male chickens are called cockerels
Female chickens, on the other hand, are called pullets when they are young and under a year old. Once they hit puberty and start laying eggs, they become hens.
It is worth noting that the terms "rooster" and "cock" are interchangeable, with "rooster" being preferred in the United States and "cock" more commonly used in the rest of the world.
In addition, the term chicken is used to refer to a baby chicken of either sex, and a group of baby chicks is called a "brood."
Chickens have distinct differences in adulthood, with males having larger combs, wattles, and pointed tail feathers, while females have rounded tail feathers.

Young female chickens are called pullets
Young female chickens are called "pullets". The term "pullet" is used to refer to female chickens under a year old, although definitions vary. Some people say that a female chicken is a "pullet" if it is under 22 weeks old, while others say that the term applies to female chickens between 12 and 16 weeks old. Some even argue that female chickens are "pullets" until their first moult, which can occur when they are 18 months old.
"Pullets" are exclusively female. They are young "teenager" birds that have not yet begun laying eggs. Once they hit puberty and start laying, they are referred to as "hens". "Hens" are sexually mature adult female chickens that have begun laying eggs. Birds usually start laying at around five months old, although this can vary depending on breed and individual birds. Most hens continue laying regularly until they are around three or four years old.
"Pullets" are also called juveniles or juvenile chickens. "Juvenile" is a term used to refer to young chickens of both sexes. "Chicks" is another term used to refer to baby chickens of either sex. However, "chicks" can also refer to chickens under 12 weeks old, regardless of sex.
"Pullets" are sometimes referred to as "biddies". "Biddy" is a colloquial term that originally referred specifically to older hens. Later, it came to refer to juvenile or mature chickens. The word likely comes from the sounds made to call the flock: "biddy-biddy-biddy".
In the poultry industry, a "pullet" is a sexually immature chicken less than 22 weeks of age.

A baby chicken of either sex is called a chick
A baby chicken of either sex is called a "chick". The word "chick" is a contraction of the word "chicken", and it applies to any chicken under 12 weeks old, regardless of sex.
Historically, it was many weeks before it was possible to tell apart male and female chicks. The Western world didn't know how to differentiate between the sexes until the 1930s, when they learned the method from the Japanese. This involved squeezing the bird and feeling for its internal reproductive organs.
Once they grow feathers instead of down, young female chickens are called "pullets", and young male chickens are called "cockerels". Male chickens become "roosters" or "cocks" once they hit puberty and begin mating, and female chickens become "hens" once they hit puberty and start laying eggs.
A group of baby chicks that all hatch at the same time is called a "brood", and historically, a group of chicks could be referred to as a "chattering of chicks" or a "peep of chicks".

Juvenile chickens is a term for young chickens of both sexes
There are many different terms used to refer to chickens of different ages and sexes. While "chicken" is the singular term, the plural form is "chickens" and not "chick" as some people incorrectly believe. "Chick" is a contraction of "chicken" and refers to a baby chicken of either sex. Another term for young chickens of both sexes is "juvenile chickens" or simply juveniles.
When they are slightly older, but still immature, female chickens are called "pullets", while male chickens are called "cockerels". A pullet is a female chicken under a year old, and in the poultry industry, the term refers specifically to a sexually immature chicken less than 22 weeks of age. A cockerel is a young male chicken under a year old that has not yet hit puberty.
Once they reach sexual maturity, female chickens are called "hens" and male chickens are called "roosters" or "cocks". Roosters and cocks are interchangeable terms, with the former being preferred in the United States and the latter being more common in the rest of the world.

A sexually mature male chicken is called a rooster
Roosters can be differentiated from hens (sexually mature female chickens) by their larger combs and wattles, as well as their pointed tail feathers, while those of hens are rounded. Roosters also crow, while hens do not.
Before reaching sexual maturity, male chickens are referred to as cockerels. Young female chickens are called pullets. Both male and female chickens under the age of 12 weeks are called chicks.
Chickens reproduce through cloacal contact, also known as the 'cloacal kiss'. Sperm transfer occurs when the male and female cloacae touch. As with all birds, reproduction is controlled by the neuroendocrine system, specifically the Gonadotropin-Releasing Hormone-I neurons in the hypothalamus.
