Determining a chick's age is important for several reasons, such as knowing when to sell a pullet or when to introduce your chicks to an older brood. The first thing to consider is the breed of your chick, as different breeds develop at different rates. For instance, some are fast-maturing, while others are slow-feathering. The external temperature and brooder temperature also play a role in the growth rate of your chick. Typically, chicks will be covered in a fine down coat until about day 6, after which feathers will begin to appear, starting with the wingtips. By the fourth week of life, all feathers should be grown in. By the seventh week, the chick will undergo its second and final mini molt, which will last until the twelfth week, during which its baby feathers will be replaced by adult plumage.

Chick feathering: wing feathers appear at one week, full feathering by week six
Chickens go through various developmental stages, and their feathering is one of the key visual indicators of their age. From hatch until day 6, chicks are covered in a fine down coat. Around day 7, the first of the chick's feathers will start to appear, usually on their wingtips. At this stage, they resemble a bad haircut. By the fourth week of life, all feathers will have grown in.
By the sixth week, most chicks are fully feathered, with their chick down gone and real feathers in its place. This allows them to regulate their body temperatures. However, not all breeds or individual chickens will be fully feathered at the same age. Some sources state that the second and final mini molt starts around the seventh week and lasts until the twelfth week, during which time the small baby feathers are replaced by the first adult plumage.
The speed of feathering is influenced by genetics and sex. The phenotypical variation among breeds can be explained by the sex-linked gene K. Sex-linked delayed feathering is typical in many meat-type breeds, such as Brahma, Cornish, Cochin, Rhode Island Red, Wyandotte, Plymouth Rock, and Orpington. Female chicks generally have slightly faster feathering than males.
In addition to age, the shape of feathers can also indicate a chick's sex. According to some sources, any pink feathers at all at three weeks of age indicate a cockerel, while pullets will have flesh-toned skin with little to no colour.

Chickens are chicks until their last mini-molt, then they're pullets
Chickens go through two juvenile or "mini molts" before their first annual molt. The first mini molt begins at 6–8 days old and is complete by approximately 4 weeks when the chick's down is replaced by its first set of feathers. The second mini molt occurs between 7 and 12 weeks of age, during which the first set of feathers are replaced by a second set. At this stage, a rooster's ornamental feathers will also appear.
Chicks are considered adolescents once they have their second set of feathers. Adolescent female chickens are called pullets, while male chickens are called cockerels. Pullets will start laying eggs at around 16 weeks old, though this can take up to 7 months for some breeds.
Therefore, a chicken is a chick until its last mini-molt, after which it is a pullet or cockerel.

Pullets start laying eggs at 20-24 weeks
A chick is considered an adolescent when it becomes a pullet or a cockerel. Pullets are young female chickens that have not yet started laying eggs. A chick becomes a pullet once it has its full set of adult feathers, which usually happens around the fourth week of life. The second and final mini molt starts around the seventh week and lasts until the twelfth week, during which the small baby feathers are replaced by adult plumage.
Pullets typically start laying eggs around the age of 16 to 24 weeks. Before they start laying, you may notice some physical and behavioural changes. For instance, the comb and wattles of a pullet will enlarge and turn bright red due to increased blood flow and higher hormones. The comb and wattles will also look somewhat waxy and plump. You may also notice a pullet jumping into nesting boxes and checking them out about one to two weeks before she starts laying.
To check if a pullet is nearing the egg-laying stage, you can examine the pelvis bones. If the three prominent bones are close together, the pullet is not ready to lay eggs yet. However, if the bones have separated, you can expect eggs soon.
It is important to provide the necessary nutrition to pullets once they reach 16 weeks of age, as laying hens require special nutrition. Producing eggs places a significant nutritional strain on a hen's body, particularly in terms of calcium. Therefore, it is recommended to switch to a layer feed that contains calcium and other essential nutrients.

Sexual differences emerge at six weeks: roosters stand taller and may crow
It is important to know the approximate age of a chicken. One way to determine the age of a chick is to observe the key visual differences at each development stage. From hatch until day 6, a chick will be covered in a fine down coat without any feathers. Around day 7, the first feathers will start to appear, usually on the wing tips. By the fourth week of life, all feathers will have grown in. The second and final mini molt will start around the seventh week and last until the twelfth week. During this time, the small baby feathers will be replaced by the first adult plumage.
At six weeks old, sexual differences will begin to emerge. Roosters may stand taller than their female counterparts and might even start to crow. Their combs will be larger and redder than female combs. Roosters will also develop a bump on the inside of their legs, where spurs will grow. The feathers on the necks, backs, and tails of young cockerels will have pointed ends. By the time they reach maturity at 16 to 20 weeks old, these feathers will become long and iridescent, forming the distinctive rooster tail, cape, and saddle.
In addition to physical characteristics, the age of a chicken can be estimated by its behaviour. From 0 to 16 weeks, chicks are dependent on a mother hen for education and survival. From 16 to 20 weeks, the mother hen will no longer take care of the chicks, marking the start of their independence. Pullets will start laying anytime after 20 to 24 weeks of age.
It is important to note that chick growth rates can vary depending on factors such as breed, temperature, care, and health.

Leg scales: older chickens have rougher, larger scales than younger ones
There are a few ways to determine a chicken's age. Firstly, you can look at their plumage. From hatch until day 6, chicks will be covered in a fine down coat with no feathers. Around day 7, the first feathers will start to appear, usually at the wingtips. By the fourth week of life, all feathers will have grown in. The second and final mini-molt will start around the seventh week and last until the twelfth week. During this time, small baby feathers will be replaced by the first adult plumage.
Another way to determine a chick's age is by looking at their legs. Older chickens tend to have rougher, larger scales on their legs than younger ones. This is due to the accumulation of mud under the scales, which can make them appear raised and rougher. Additionally, the colour of the legs can indicate age. For the first few weeks, a chick's legs will be very light, and they will darken over time.
It is important to note that some chickens may appear older or younger than they are due to their breed or individual growth rate. However, these visual indicators can provide a general sense of a chicken's age.

There are a few ways to determine the age of a chick:
- Within the first week of hatching, chicks are covered in a fine down coat with no feathers.
- By the end of the first week, tiny feathers will begin to sprout on their wings.
- By the fourth week, all feathers should be grown in, although the chick will look like it has a bad haircut.
- At six weeks old, the chick will have completed feathering and sexual differences will begin to emerge. Roosters may stand taller than their female counterparts and might even start to crow.
- At seven weeks old, the chick will undergo its second and final mini molt, which will last until the twelfth week. During this time, small baby feathers will be replaced by adult plumage.
The first feathers of a chick will appear around the wing tips by the end of the first week. By the fourth week, all feathers should be grown in. By the sixth week, the chick will have completed feathering.
Young birds often don't reach their full adult weight or size until they are almost a year old.
Chicks are dependent on their mother hen for education and survival until they are around 16 weeks old. From 16 to 20 weeks old, they will start to become independent and the mother will no longer take care of them.
Chickens of both sexes tend to have small, fine scales on their legs. As they age, these scales shed and larger, rougher scales will appear.
