While it can be difficult to determine a chick's gender, there are some methods that can help you distinguish between a rooster and a hen chick. One way is to examine the physical characteristics of the chick, such as feather patterns, size and build, combs and wattles, and spur growth. Another method is to observe the behaviour of the chick, including vocalizations and egg-laying behaviour. In addition, the sex of a chick can be determined by using techniques such as sexual dimorphism, auto-sexing breeds, sex-linked breeds, and vent sexing. However, the accuracy of these methods may vary, and it is generally easier to distinguish between roosters and hens once they have matured.

What You'll Learn
Observe feather patterns and colours
Observing the feather patterns and colours of chicks is one of the methods to determine whether a chick is a rooster or a hen. This method is called auto-sexing or colour-linked sexing and it works only for specific breeds that present different colourations for males and females.
One example of auto-sexing is the black sex-link breed, where the male chicks have white spots on their heads, while the female chicks have more noticeable lines and blotches that appear like triangular patches. Another example is the Barred Rock breed, where the males have a more diffused yellow spot on their heads, while the females have darker and more "smudged" barring. Similarly, the male Rhode Island Red and New Hampshire chicks have a white spot on the down over the wing web, a feature that is lost when they grow up.
In some breeds, male and female chicks develop wing feathers at different rates. Females usually have longer primary wing feathers, while males have shorter, more uniform feathers. This method is called feather-linked sexing or feather sexing.
When chickens are around three to six months old, you can observe the development of their secondary feathers as they approach sexual maturity. The most distinctive are the hackle, saddle, and tail feathers. The hackle feathers, also known as neck feathers, are longer and pointier in roosters, while they are shorter and rounder in hens. The tail feathers of roosters are pointier and showier, sometimes with several different colours, while the tail feathers of hens are broad, straight, and full. Roosters also have long saddle feathers that grow on their backs towards their tails, while hens have rounded ones.

Look out for physical differences, such as comb and wattle size
When distinguishing between a rooster and a hen chick, one of the key indicators is the size of their comb and wattles. Roosters generally have larger combs and wattles than hens. The comb and wattles of a rooster are also often redder and brighter in colour. However, it is important to note that this may not be true for all breeds, and there can be variations in comb and wattle size within the same breed. For example, a Leghorn hen could have a larger comb than roosters of a different breed. Therefore, it is crucial to compare the size and colour of the comb and wattles between males and females of the same breed to make an accurate determination.
The comb of a rooster is typically larger, waxy to the touch, and bright red, while the comb of a hen is smaller and less vibrant. Roosters of certain breeds may also develop larger combs at an earlier age than hens. Additionally, the wattles of a rooster are usually larger and longer than those of a hen. Bearded chicken breeds, such as Faverolle chickens, Silkies, and bearded-Polish chickens, often lack wattles or have very small ones that are obscured by their beard feathers.
It is worth noting that the size and colour of a hen's comb and wattles can vary depending on their productivity and health. A healthy and productive hen who is laying eggs will have a larger and brighter comb compared to a hen who is not laying. On the other hand, during the fall molt or shorter winter days, a hen's comb may shrink in size, indicating a decrease in productivity. Additionally, small, shrivelled, and pale wattles can be a sign of poor health in both roosters and hens.
While comb and wattle size can be an indicator of sex, it may not always be a definitive method of differentiation. Other physical characteristics, such as size and build, can also be considered. Roosters tend to be larger and more robust, with thicker legs and a more upright posture. Hens, on the other hand, have a more rounded body and a lower stance.

Listen for vocalisations and crowing
While vocalisations and crowing are often associated with roosters, hens can also make these sounds.
Hens may crow to establish their place in the pecking order, imitating the behaviour of roosters to assert their dominance and establish a territory. This is more likely to occur if there is no rooster in the flock, or if a hen is challenging the rooster for dominance. In some cases, a hen may develop male sex hormones, causing her to adopt rooster characteristics, including crowing. However, the crow of a hen will not sound exactly like that of a rooster and may sound terse and strangled.
Roosters, on the other hand, are known for their loud and noisy crowing. They make several different noises, each with its own meaning. For example, a rooster may make a deep and abrupt "oo-oo" sound to warn of danger or an aerial threat. Hens are able to understand these vocalisations and will react accordingly, such as by running for cover.
In terms of vocalisations, it is important to note that hens also have a variety of calls. For example, a content hen may make a peaceful, calm, and slow murmuring sound. Hens may also make an alarm call or a food call when they find good food, which the rest of the flock will then draw in to eat.
While it may be challenging for new chicken owners to differentiate between the crowing of a hen and a rooster, with time and experience, it is possible to become more adept at distinguishing these sounds.

Identify egg-laying behaviour
Identifying egg-laying behaviour in hens can be tricky, especially in chicks, as there is no 100% accurate assessment method. However, there are some signs to look out for that indicate a hen is ready to lay eggs.
Firstly, watch out for physical signs of maturity. As a hen matures, its comb and wattles will become larger and redder, and its face will change from light pink to a brighter red. The vent, from which the hen releases eggs, will also become larger and redder, and may change from dry to moist. The pelvic bones will also separate to make room for the eggs to pass through.
Secondly, observe the hen's behaviour. A hen will start preparing its nesting area when it is ready to lay. It will spend more time in this area, rearranging the bedding to its liking. It may also begin to test out the nest by sitting inside, even if it isn't quite ready to lay yet. The hen may also become more vocal and talkative before laying an egg, and may sing and squawk for hours.
Another behavioural sign is the "submissive squat". When a human approaches, the hen may stop, squat, and put its wings out slightly to its sides. This is a sign of submission and is often seen in hens that are ready to lay.
Finally, observe the hen's eating habits. As a hen gears up to lay eggs, its body will go through many changes, and it will require more energy. You may notice the hen eating more than usual to meet these increased energy demands.
By observing these physical and behavioural changes, you can identify when a hen is ready to start laying eggs.

Watch for behavioural cues
Behavioural cues are an important way to differentiate between rooster and hen chicks. As chicks grow, their behaviour can provide clues as to their gender. Males may start exhibiting more dominant behaviours, such as play fighting and assertive pecking. Roosters are designed to attract attention, with their flashy appearance and energetic behaviour. They are also more assertive and bossy, even when young. They will challenge each other as they get older, raising their hackle feathers.
Roosters are flock leaders, keeping subordinates in line and mating with the hens as frequently as possible. They are watchful and rarely eat until the hens have finished. They herd the hens, keeping a lookout for predators or unusual things. If they sense danger, they sound the alarm and lead the hens away.
Hens, on the other hand, are more timid and tend to have a more rounded body and a lower stance. They are also smaller, which helps them move quickly to avoid danger. They are incredibly useful for hatching and raising chicks, doing far better than any incubator.
It is important to note that these behaviours may not be apparent in very young chicks, and it can be challenging to determine their gender at this stage. As chicks mature, their behaviours will become more pronounced, and it will be easier to differentiate between roosters and hens.

Frequently asked questions
It can be difficult to determine a chick's gender, but here are some ways to try:
- Observe the down colour. Breed-specific combinations of rooster and hen provided an accurate identification factor for males and females, but it only works with certain breeds.
- Look at their combs. Roosters have larger and brighter red combs that will feel waxy to the touch.
- Observe their feathers. Roosters will have longer and more pointed hackle and saddle feathers, while hens will have rounded feathers.
- Look at their legs. Roosters tend to have sturdier and thicker legs.
One of the most obvious ways is by their vocalisations. Roosters are known for their noisy crowing, which they start doing at around five months old. While hens can also crow, it is a lot less common and quieter.
It is a lot easier to tell a rooster from a hen once they are adults. Apart from the above characteristics, you can observe the following:
- Roosters will have longer tail feathers that form an impressive fan-like display.
- Roosters are more protective and territorial.
- Hens are the ones responsible for laying eggs.
