Telling a hen chicken from a rooster can be tricky, especially when they are young. There are, however, some observable differences in external appearance and behaviour that can help you distinguish between the two. While some of these differences are more pronounced in certain breeds, they are generally applicable across most chicken breeds.

Observe their feathers: Rooster feathers are long and pointy, while hen feathers are rounded
One of the most significant ways to differentiate between a hen and a rooster is by observing their feathers. Rooster feathers are typically longer and more pointed, while hen feathers are shorter and rounded.
Let's take a closer look at the different types of feathers and how they vary between roosters and hens:
Neck Feathers (Hackle Feathers)
Roosters have long and pointy hackle feathers, which adorn their necks and cascade down onto their shoulders. On the other hand, hens' hackle feathers are shorter and rounder, making them less noticeable.
Tail Feathers
Roosters are known for their long, sickle-shaped tail feathers, which curve upwards and gracefully arc downwards. These feathers are often more vibrant and showy, sometimes featuring several different colours. In contrast, hens have shorter, straighter, and less ornate tail feathers.
Saddle Feathers
Saddle feathers grow on the back of the chicken, extending downwards towards the tail. Cockerels, or young male chickens, will develop long and pointed saddle feathers by the time they are about three months old. Hens, on the other hand, will have rounded saddle feathers.
Wing Feathers
While not specifically mentioned as a distinguishing feature in the sources provided, one source does mention that in some breeds, male and female chicks develop wing feathers at different rates. Females typically develop longer primary wing feathers, while males have shorter, more uniform feathers.
It is important to note that not all breeds of chickens have the same distinguishing features when it comes to feathers. Some breeds may have different patterns or colour variations that can help identify the sex, but these are not consistent across all chickens. Additionally, the absence of long, fancy tail feathers does not automatically indicate that a chicken is female, as chickens can lose their feathers during moulting or due to trauma.

Check their combs: Roosters have larger, redder combs than hens
One of the most notable differences between a hen chicken and a rooster is their comb size and colour. Roosters have larger, redder combs than hens, which develop at an earlier age. The comb is a fleshy growth on the top of a chicken's head, and roosters use their large combs to attract hens and signal their sexual maturity. Hens tend to be attracted to roosters with larger, brighter combs as they indicate health and well-being.
In addition to comb size, roosters also have more pronounced wattles, which are the elongated, fleshy skin that hangs under the beak. Both sexes have wattles, but roosters' wattles are typically larger and redder. As with combs, roosters' wattles become more pronounced at a younger age than those of hens.
The size and colour of combs and wattles can be a reliable indicator of a chicken's sex, especially when trying to differentiate between young chicks. Chicks that are likely to be roosters will have larger combs and wattles that develop earlier, whereas those that are likely to be hens will have smaller, more petite features.
It's worth noting that not all chicken breeds have noticeable differences in comb and wattle size. For example, Polish chickens can be challenging to sex at a young age, and Silkies are one of the most difficult breeds to sex due to their unique characteristics. However, for most breeds, comb and wattle size and colour can be a helpful indicator of a chicken's sex.
In addition to comb and wattle size, there are other physical differences between hen chickens and roosters. Roosters typically have thicker legs, longer and pointier neck and saddle feathers, and more vibrant and varied plumage. They also carry themselves more upright due to their larger and more robust build. Hens, on the other hand, have a more rounded body, shorter and rounder feathers, and more subdued colours.

Examine their legs: Rooster legs are larger and stronger than those of hens
One of the ways to differentiate between a hen and a rooster is by examining their legs. Rooster legs are larger, stronger, and thicker than those of hens. They also have pointed, sharp spurs on their legs just above their toes, which they use for defence and establishing dominance. The spurs on a rooster's legs can be as long as more than an inch, while hens may have small, undeveloped spurs or none at all.
While examining the legs, you may also notice buds on the rooster's legs, indicating that spurs will develop later. The purpose of these spurs is to project health and strength. However, it is important to note that not all roosters will have spurs, and some hens may develop spurs as they age, although they are typically less pronounced than those on mature roosters.
In addition to larger and stronger legs, roosters also tend to have larger feet than hens. This combination of larger legs and feet contributes to the overall stockier build that is characteristic of roosters.
Leg size and the presence of spurs can be a reliable method for differentiating between young roosters and hens for a short period of time. However, as chickens age, other characteristics such as comb size, wattles, and plumage may become more prominent indicators of their sex.
It is worth noting that different breeds of chickens may exhibit slight variations in these characteristics, so it is always helpful to compare chickens of the same breed when trying to determine the sex based on physical traits.

Listen for a crow: Only roosters crow
The crow of a rooster is a classic, unmistakable sound. Roosters will crow throughout the day, but their most enthusiastic crowing occurs early in the morning as they greet the sunrise. The purpose of their crowing is to define and defend their territory. Roosters with a higher rank in the pecking order will perch up high and crow in the direction of neighbouring roosters.
Hens, on the other hand, do not crow. However, it is possible for hens to crow if they have a hormonal imbalance, but this is a rare occurrence. Hens will also listen out for the sounds of the rooster as they are meant for her. The rooster constantly scans the sky and his hens, protecting his ladies. If a hen is lost, she will make a cry of worry, to which her rooster will crow in response, allowing her to locate him.
The rooster also makes other sounds to communicate with his flock. For example, a loud, deep and abrupt "oo-oo" sound indicates danger, specifically an aerial threat. If the "oo-oo" is subtle, the hens will scan the sky for danger, but if the sound is strong, they will run for cover. Roosters also make a high-pitched excited "coo" sound when they have found food.
Therefore, listening out for the crow is a good way to distinguish a rooster from a hen.

Watch their behaviour: Roosters are more assertive and territorial
Behavioural observations can be a great way to determine whether a chicken is a rooster or a hen. While it can be challenging to determine the sex of young chicks, as they mature, their behaviours can provide clues.
Roosters are known for their protective and territorial nature. They are more assertive and bossy, even at a young age. They may start exhibiting dominant behaviours such as play-fighting and assertive pecking. As they get older, roosters will begin to challenge each other, raising their hackle feathers. They may also display dominance by strutting, fluffing their feathers, and crowing.
On the other hand, hens are generally more docile and timid. They are focused on nesting and foraging and do not exhibit the same aggressive behaviours as roosters.
Additionally, roosters will often crow throughout the day, especially enthusiastically in the morning as they greet the sunrise. Hens do not typically crow, although there may be exceptions.
Egg-laying is another practical way to determine the sex of a chicken. Hens are the ones responsible for producing eggs, so if a chicken is laying eggs, it is safe to assume it is a hen. However, it is important to note that hens do not usually start laying eggs until around six months of age, so this method may not be useful for younger chickens.

Frequently asked questions
There are several observable differences between adult roosters and hens, including:
- Roosters have larger, more colourful combs and wattles.
- Roosters have longer and more pronounced neck and tail feathers, while hens have softer, more subdued feathers.
- Roosters are more assertive and territorial, while hens are more docile.
- Only roosters crow.
- Only hens lay eggs.
It is difficult to accurately identify the sex of a chick. However, some methods you can use include:
- Sexual dimorphism: Identifying physical and behavioural characteristics as the chick matures.
- Auto-sexing: Some breeds of chickens have different colour patterns depending on their sex.
- Vent sexing: Examining the sex organs of a chick.
One method that can be used at home is to hold the chick in the air above its wings. If it moves around and pulls its legs up, it is likely a rooster. If it lets its legs hang or sticks them out, it is likely a hen. However, some sources state the opposite, so this method may not be reliable.
