Determining the sex of a chicken is called sexing, and it is much simpler and more accurate to sex adult birds than chicks. Roosters and hens differ in several ways, including physical appearance and behaviour. Some of the physical differences between the sexes include the size of their combs, wattles, feet and legs, as well as the shape of their feathers. Behavioural differences include aggression and dominance, with roosters more likely to fight and assert their dominance over other roosters.
| Characteristics | Values |
|---|---|
| Behaviour | Roosters are generally more assertive, outgoing, and aggressive than hens. Roosters are also said to always have an eye out for danger, ready to fight to protect their flock. |
| Body Development | Roosters are larger, with darker pink combs and wattles that grow faster and larger than those of hens. |
| Feathers | Roosters have long, pointy, and thin hackle feathers, while hens have rounded hackle feathers. Roosters also have more dramatic saddle feathers. |
| Legs | Roosters have larger, stronger, and more robust legs than hens. |
| Eggs | The shape of eggs can vary among hens, with some laying more rounded eggs than others. |
| Auto-sexing Breeds | Some breeds, such as Purebred Cuckoo Maran, have different coloring patterns between males and females, making it possible to identify their sex at a very early age. |

Behavioural differences: Roosters are more assertive and outgoing, with a tendency to fight
Behavioural differences can be a helpful indicator of the sex of a chick, as physical differences can be hard to spot. Roosters are generally more assertive and outgoing than hens. They may also be more personable and friendly, at least until their hormones kick in. As they get older, they will start to challenge each other, raising their hackle feathers.
Males may start exhibiting more dominant behaviours at an early age, such as play fighting and assertive pecking. Roosters will also crow in the morning, which is a clear indicator of their sex. The rooster that matures first will also assert dominance, and the remaining cockerels will try to escape the coop.
As chicks, roosters will also have shorter primary and secondary wing feathers, and they feather more slowly. They will also have pointier hackle feathers (neck feathers) and saddle feathers (feathers on the back, down towards the tail).

Physical differences: Roosters are larger with redder combs and wattles
One of the most noticeable physical differences between roosters and hens is the size of their combs and wattles. Roosters typically have larger, well-developed, and redder combs and wattles than hens. The comb is the fleshy growth on top of a chicken's head, and the wattles are the pair of fleshy growths hanging below the chicken's beak.
The colour and size of a chicken's comb and wattles can indicate their health and productivity. Roosters use their combs to signal to hens that they are sexually mature, with hens tending to favour roosters with larger, brighter combs. The brightness and size of a hen's comb can also indicate whether or not she is laying eggs. During the fall moult or shorter winter days, a hen's comb may shrink, indicating that she has stopped laying.
While roosters generally have larger combs and wattles, it's important to note that the size and colour of these features can vary depending on the breed of chicken. For example, bearded chicken breeds, such as Faverolles, Silkies, and bearded-Polish chickens, tend to have little to no wattles. Additionally, some breeds, like Brahmas, take longer for their combs to develop.
Another physical difference between roosters and hens is the shape of their feathers. Roosters' hackle and saddle feathers (the feathers at the base of the neck and where the back meets the tail, respectively) tend to be longer and pointier, while hens' feathers in these areas are more rounded. These differences become more noticeable as the chickens mature, typically around 8 to 10 weeks of age.
Finally, roosters tend to have larger, stronger, and more robust feet and legs than hens. Even before the spurs form, you may notice buds developing where they will eventually appear. These physical differences contribute to the overall flashier appearance of roosters, which has evolved to attract mates and deter predators.

Leg differences: Roosters have larger, stronger legs with spurs
While it is challenging to determine the sex of a chick, one identifying factor is leg differences. Roosters have larger, stronger legs with spurs, which are pointed, claw-like outgrowths on the back of each leg. These outgrowths have a slight curvature and resemble an extra toe with a sharp point. The purpose of these spurs is to signal health and strength, as well as to protect the flock and defend their territory.
All chickens have a small bump or spur bud on the back of their legs, which typically remains dormant in hens. However, some breeds of hens, particularly Mediterranean breeds such as Leghorns, Minorca, Sicilian Buttercups, Anconas, and Polish hens, are more likely to develop spurs as they age. These spurs can sometimes grow quite long and may require trimming or filing to prevent them from becoming a hindrance when walking or curling back and cutting into the leg.
As chicks grow older, the reliability of using leg sexing as an identification method decreases. Even before spurs develop, you may observe buds where they will eventually form. Roosters' legs are generally larger and more robust than those of hens, but this method of sexing is most reliable for a short period of time.
It is important to note that not all roosters will exhibit the same behaviours or physical characteristics. Some roosters may be docile, while others may become aggressive and require careful management to prevent attacks. Additionally, the presence or absence of spurs should not be the sole factor in determining the sex of a chick, as both roosters and hens can develop spurs, albeit with different levels of prevalence and distinctiveness.

Feather differences: Rooster feathers are longer and pointier, hen feathers are rounded
When it comes to differentiating between a hen and a rooster chick, it is much simpler and more accurate to sex adult birds. This is because chickens have internal sex organs, so there is nothing visually noticeable to distinguish between the two. However, there are some observable differences in external appearance and behaviour that can be used to tell the difference.
One of the most prominent ways to differentiate between a hen and a rooster chick is by looking at their feathers. Rooster feathers tend to be longer and pointier, especially in the neck (hackles), back (saddle feathers), and tail. On the other hand, hen feathers are shorter and rounded. The difference in the shape of feathers is one of the first accurate indicators of whether a chick is male or female. The neck feathers of male chicks will have pointed tips like a "V", while female neck feathers are usually rounded at the tip.
In addition to the shape, the texture of the feathers also differs between roosters and hens. Roosters have pointier and shinier feathers, while hens have softer feathers. The colour of the feathers can also vary between the two sexes, with roosters having more vibrant tail feathers.
The presence of certain types of feathers can also be indicative of the sex of the chick. Roosters have long saddle feathers with pointed tips that drape downward from the base of the tail. They also have prominent sickle feathers in their tails, which are long and arched. Hens, on the other hand, do not have these distinctive saddle and sickle feathers.
While the shape, texture, and colour of feathers can provide clues about the sex of a chick, it is important to note that there is variation among different breeds of chickens. Some breeds, such as Silver Leghorns, have both sexes developing spurs, while others like the Silkie or Golden Campine have roosters that are "hen-feathered", lacking the typical saddle and sickle feathers. Additionally, the rate of feather development can vary between roosters and hens, with male chicks sometimes growing tail feathers later than females.

Auto-sexing breeds: Some breeds have different colour patterns at birth
Auto-sexing breeds are purebred chickens that can be visually distinguished between male and female chicks from the day they hatch. These breeds have different colour patterns at birth, which is a highly desirable characteristic as it allows farmers to select and raise females as guaranteed pullets, keeping feed costs down.
The first auto-sexing breed was the Gold Cambar, exhibited by Dr. Reginald Punnett at the World Poultry Congress in 1930. Punnett hypothesised that the gene for barred colour patterns acted differently in male and female chicks. He found that by crossing brown-coloured males with barred silver females, the male chicks would be lighter in colour and more barred, while female chicks would have clearly defined "chipmunk stripes" on their backs.
The Cream Legbar is one of the most well-known examples of auto-sexing breeds. It was created from a cross between the Brown Leghorn, Araucana, and Barred Plymouth Rock. Male Legbar chicks have a slight barring pattern, while females have chipmunk striping on their backs. The barring pattern is sex-linked, with males having two barring chromosomes and females having only one. As a result, male chicks have a light-coloured patch on the top of their heads, while females have a small, well-defined dark brown stripe down their backs.
Other auto-sexing breeds include the Rhodebar, Wybar, Barnebar, Brussbar, and Welbar, which were developed in the UK, as well as the Bielefelder, which was developed in Germany in the 1970s.

Frequently asked questions
You can't. Unlike mammals, poultry sex organs are internal, so there are no visual cues.
It's difficult, but some breeds of chickens are auto-sexing, meaning males and females hatch with different colour patterns.
You can use the method of sexual dimorphism, which involves looking for observable changes in behaviour or appearance.
Look at their feathers, particularly the hackle feathers around the neck and the saddle feathers near the tail. Male hackle feathers are longer, pointier, and thinner, while female hackle feathers are smaller, rounder, and softer. Male saddle feathers are also longer and more pointed, while female saddle feathers are rounder.
Roosters have larger combs and wattles, which are also brighter in colour. Roosters also have sturdier, thicker legs, and spurs on their shanks.
