What You'll Learn

A mature male chicken is called a rooster
Young male chickens that have not reached sexual maturity are called cockerels. Roosters are sexually mature male chickens, meaning they are attracted to female chickens. There are no clear physical markers to indicate when a male bird becomes a rooster, but the term is generally applied to male birds over one year old.
Female chickens are called hens, and young female chickens are called pullets. A hen is considered sexually mature when it starts laying eggs, which usually happens around five months of age.
Roosters, like all chickens, typically eat the same things. However, they require a higher protein diet during the breeding season to ensure good hatchability of the eggs. Roosters also need regular spur and toenail trimming, as their spurs can grow long and curve, causing lameness if left unattended.

A young male chicken is called a cockerel
The term "cockerel" is also used interchangeably with "pullet" to refer to young chickens of either sex that have grown feathers instead of down. "Pullet", however, specifically refers to a young female chicken.
"Cockerel" is also used to refer to a male chicken under one year old, hatched during the current calendar year, or one that has not hit puberty and begun mating.
A fully mature male chicken is called a rooster or cock. Roosters are sexually mature male chickens, and the term is applied to any male bird over one year old. The word "cock" is derived from the Old French "coc" or "coq", meaning male bird. The term "cock" is more commonly used outside of the United States.
"Hen" is the term used for a sexually mature female chicken that has reached sexual maturity and begun laying eggs.

A male chicken is called a cock, derived from Old French
A male chicken is typically called a rooster. However, the term cock, derived from the Old French coc or coq, is also used to refer to a mature male chicken. The word 'cock' is used more commonly outside of the United States, while 'rooster' is the preferred term in the US.
The word 'cock' has a long and varied history. Initially, it simply meant a male bird. However, as language evolved, it took on a life of its own. The term 'cock of the walk' was used to describe a vain and boastful man, strutting around like a cock in a chicken yard. Over time, it took on a more explicit sexual connotation.
The original term for a male chicken was 'roost cock', referring to a roosting bird. However, the sexual connotations of the word 'cock' disturbed the Puritans, who changed the designation to 'rooster'.
Today, the term 'cock' is still used interchangeably with 'rooster' outside of the US. However, some farmers and breeders may avoid using the term 'cock' due to its vulgar slang usage.
To add to the confusion, there are several other terms used to describe male chickens at different stages of development. A young male chicken that is fully feathered but has not yet reached sexual maturity is called a cockerel. A capon is a castrated male chicken, producing a larger, fatter bird.

Roosters require a higher protein diet for good hatchability of eggs
A mature male chicken is commonly known as a rooster. While hens are usually the centre of attention in backyard chicken setups due to their egg-laying abilities, roosters play an important role in protecting the flock and ensuring the hens are well-guarded. Roosters also contribute to flock growth through the fertilization of eggs.
In addition to protein, roosters require specific nutrients such as omega-3 and omega-6 fatty acids, which support sperm health and viability. Vitamin E and selenium, potent antioxidants, also play a crucial role in protecting sperm cells from damage. It is important to ensure that breeder flocks have enough to eat, as a negative energy balance can negatively impact fertility and hatchability.
While roosters require higher protein content in their diet, they need less calcium than laying hens. Laying hens require 3 to 5% calcium in their diet to produce strong eggshells, whereas roosters only need about 1% calcium to maintain healthy bones and bodily functions. This difference in nutritional requirements means that roosters should be fed a separate diet optimised for their needs.
Overall, a rooster's diet is of utmost importance not only for the viability of hatching eggs but also for the quality of their semen. By ensuring that roosters consume sufficient protein and essential nutrients, breeders can optimise the hatchability of eggs and maintain the health and longevity of their roosters.

Roosters can become aggressive due to feeling threatened
A male chicken is commonly known as a rooster. Roosters are known to exhibit aggressive behaviour due to a variety of factors, often related to feeling threatened.
Roosters can become aggressive due to a perceived threat to their safety or the safety of their flock. They have a strong instinct to protect their flock and will attack or fight to defend them. This behaviour is not driven by meanness but rather by survival instincts that would have been advantageous in the wild. Roosters may also exhibit aggression when attempting to establish dominance within the flock or among humans. They may view humans as potential rivals and assert themselves as dominant by acting aggressively.
Hormones play a significant role in rooster aggression. Young roosters who have recently reached sexual maturity experience a surge in testosterone levels, resulting in heightened energy and excitement. This hormonal influence can lead to aggressive behaviour as they test their boundaries. However, as roosters age, their testosterone levels decrease, and by their third year, they become noticeably more sedate and pleasant.
Environmental stressors can also trigger aggression in roosters. Stressful conditions, such as extreme temperatures or a lack of adequate predator protection, can contribute to heightened aggression. Additionally, certain behaviours exhibited by humans can be perceived as threatening by roosters, increasing the likelihood of aggressive responses. These behaviours include chasing their hens, acting stealthily, or crowding the rooster's space.
Genetics and learned behaviours also influence rooster aggression. Some breeds are genetically predisposed to be more aggressive, and individual roosters within those breeds may exhibit varying levels of aggression. Learned behaviours from other chickens or humans can further contribute to aggressive tendencies.
Understanding the underlying causes of rooster aggression is crucial for effectively managing and deterring aggressive behaviour. Various strategies, such as de-escalation techniques, isolation, and providing mental stimulation, can be employed to prevent aggressive incidents, ensuring the safety of both the roosters and those around them.
