The chicken is a species of bird that includes both hens and roosters, with chicken being a gender-neutral term. A male chicken is considered a cockerel before one year of age, after which he is considered a rooster. Roosters have more defined combs and wattles than chickens, meaning the red crown atop their heads is larger. Roosters also have longer, more flowing, and more colourful tail feathers, and their hackle feathers (neck feathers) are longer and more pointed. Roosters are also larger and broader-bodied than chickens, and they have more defined feet, with some developing pointed spurs on their legs.

What You'll Learn
Male chickens under one year old are called cockerels
The terms "rooster" and "chicken" are often used interchangeably to refer to male chickens. However, there is a distinction between the two terms. While "chicken" is a broad term encompassing birds of either gender, "rooster" specifically refers to an adult male chicken. Male chickens under one year old are called cockerels, and they are considered sexually immature. Once they reach sexual maturity, usually between 20 to 25 weeks of age, they are then referred to as roosters.
Determining the sex of chicks can be challenging, and even experts can only achieve about 90% accuracy. One method for sexing chicks is auto-sexing, which involves examining the colour, pattern, or distinguishing characteristics of a chick's down feathers immediately after hatching. This method is only effective for certain breeds that exhibit different colourations or markings for males and females. For example, male Silver Leghorn chicks have lighter dorsal stripes, while female Silver Leghorn chicks have darker dorsal stripes.
As cockerels mature, they develop larger, brighter, and more pronounced combs (the red crest on top of their heads) compared to female chicks, known as pullets. Cockerels may also exhibit larger wattles, the elongated fleshy skin that hangs under their beaks, which helps them stay cool. Neck feathers, or hackle feathers, tend to be longer and pointier on cockerels, while those of pullets are rounder and shorter. Additionally, cockerels may develop saddle feathers, which grow on their backs toward their tails, and these become more noticeable as they age.
Behavioural differences may also emerge as cockerels mature. Roosters are typically more assertive and bossy, even at a young age. They may begin to challenge each other as they get older, and they are responsible for protecting their flock from predators. Consequently, they have a distinctive barnyard call that they use throughout the day to communicate with their flock.

Male chickens have larger combs and wattles
The terms "rooster" and "chicken" refer to the same bird species, Gallus gallus domesticus, but "rooster" specifically denotes male chickens, while "chicken" can refer to either male or female chickens. As chickens mature, their combs—the crest-like growth on top of their heads—grow in size and darken in colour. Male chickens, or roosters, tend to have larger and brighter combs than female chickens, though this is not always the case. Male chickens also tend to have larger wattles, the elongated, fleshy skin that hangs under the beak, which helps chickens stay cool during warm weather.
Male chickens under one year old are called cockerels, while female chickens under one year old are called pullets. After a year, male chickens are considered roosters, while female chickens become hens. The comb and wattle size of a chicken can be used to determine its gender, but this method is not always accurate.
Other methods for determining the gender of a chicken include auto-sexing, which involves examining the colour, pattern, or distinguishing characteristics of a chick's down feathers immediately after it hatches. This method only works on certain breeds that exhibit different colourations for males and females. For instance, male Silver Leghorn chickens have lighter dorsal stripes, while females have darker dorsal stripes.
In addition to comb and wattle size, there are other physical differences between male and female chickens. Male chickens tend to have thicker legs, longer neck feathers, and more pointed tail feathers. Male chickens also tend to be more assertive and bossy, while females are more timid.

Roosters have longer, pointier hackle feathers
The terms "chicken", "rooster", and "hen" refer to different aspects of the same species, Gallus gallus domesticus. "Chicken" is a general term for the species, encompassing both males and females of all ages. "Rooster" refers specifically to an adult male chicken, while "hen" refers to an adult female chicken.
Young male chickens under one year old are called cockerels, and young female chickens under one year old are called pullets.
One of the ways to distinguish between a rooster and a hen is by looking at their hackle feathers, also known as neck feathers. Roosters have longer and pointier hackle feathers, while hens have rounder and shorter hackle feathers. These feathers are located in the neck, saddle, and tail regions.
Other physical differences include the comb, which is the crest-like growth on top of a chicken's head. Roosters have larger, brighter, and more defined combs than hens. Similarly, roosters have larger and brighter wattles, which are the elongated fleshy skin that hangs under the beak and helps chickens stay cool.
Behavioural differences also exist between roosters and hens. Roosters are bossy and assertive, while hens tend to be more timid. Roosters are responsible for protecting their flock from predators and thus have a wide variety of calls and sounds to communicate with their flock. They also have a unique morphological feature in their outer ear canal that allows it to close completely when they crow to protect their hearing.

Roosters have pointed spurs on their legs
While the terms "chicken", "rooster", and "hen" are often used interchangeably, there are distinct differences between them. "Chicken" is a broad term for the species Gallus gallus domesticus, encompassing birds of either gender. "Rooster" refers specifically to an adult male chicken, while "hen" refers to an adult female chicken.
Young male chickens below one year old are called cockerels, and they eventually become roosters. One of the ways to distinguish a cockerel or rooster from a female chicken is by observing their legs and feet. Male chickens have thicker legs and more defined feet than female chickens. Roosters also often have pointed spurs on their legs, just above their toes, which they use to defend themselves. These spurs grow in the opposite direction from the rest of their toes and can be over an inch long in older roosters.
Silkies, a breed of chicken, are one of the hardest breeds to sex at a young age. However, one of the ways to distinguish a young male Silkie is by its stockier body and thicker legs.
Other physical differences between roosters and chickens include the size and colour of their combs and wattles. Roosters have larger and brighter combs and wattles, which are the red crown and skin that hang down from under their beaks, respectively. Roosters also have longer and more pointed hackle or neck feathers, as well as longer and more flowing tail feathers, which are often more colourful.

Roosters are louder and communicate more
While the terms "chicken", "rooster", and "hen" are often used interchangeably, they have distinct meanings. "Chicken" is a general term for the species Gallus gallus domesticus, encompassing all birds of this species, regardless of gender or age. "Rooster", on the other hand, specifically refers to an adult male chicken, while "hen" refers to an adult female chicken.
Roosters are known to be louder and more vocal than chickens, with a wide variety of calls and sounds that they use throughout the day to communicate with their flock. This is because, as the alpha male, the rooster is responsible for protecting the flock from any potential threats or predators. Their vocalisations serve as a warning system for the rest of the flock. Roosters also have a trademark barnyard call, the famous "cock-a-doodle-do", which they crow in the morning. Interestingly, roosters have a unique morphological feature in their outer ear canal that allows it to close completely when they crow, protecting their hearing from the high sound pressure levels they produce.
The differences in vocalisations between roosters and chickens can be attributed to their distinct roles within the flock. Roosters are the leaders of the flock, exhibiting assertive and aggressive behaviour to defend their territory. They are easily identifiable by their larger and brighter combs and wattles, which are the fleshy red crest and skin hanging beneath the beak, respectively. These physical attributes are more defined in roosters than in chickens.
In summary, while all roosters are chickens in the broader sense of the term, when referring to specific genders, it is important to distinguish between roosters (male) and hens (female). Roosters are louder and communicate more frequently due to their protective role as the alpha male of the flock.

Frequently asked questions
No. A male chicken is considered a cockerel before the age of one. After turning one, he is considered a rooster.
Roosters have more defined combs and wattles than chickens, meaning the red crown atop their heads is larger. The wattles, or the red skin beneath their beaks, are also larger. Roosters also have broader bodies, longer and more flowing tail feathers, and sharper hackle feathers (neck feathers).
Yes. Roosters are more assertive and bossy, and they will challenge each other as they get older. They are also responsible for mating with many chickens to fertilise eggs and grow the flock.
It is difficult to identify the gender of a young chick. One method is auto-sexing, which is based on the colour, pattern, or distinguishing characteristics of a chick's down feathers. Another method is sexual dimorphism, which involves looking for observable changes in behaviour or appearance as the chick matures.
"Chicken" is a gender-neutral term for the species, while "rooster" specifically refers to a male chicken.
