Determining the age of a chicken is a tricky task, especially if it's a fully grown bird. There are some visual clues and behaviours that can help you make an educated guess, but it's important to remember that many of these are not hard and fast rules. Young birds are the easiest to identify as they have a fluffy yellow coating called 'down' for the first week or so of their lives. After this, they gradually lose their down and small feathers begin to grow. A chicken is considered a chick until it sheds all its down, which usually takes around 12 weeks. From 12 to 20 weeks old, a chicken is known as a 'pullet', and during this time, its comb and wattles will become brighter and more pronounced. Once a pullet lays its first egg, it is considered an adult. For the first two years of adulthood, hens and cocks will be in their prime, with vibrant feathers, smoother legs, and colourful combs and wattles. After this, hens will slow down in egg-laying, and their combs will lose their red colour. Older hens will also develop wrinkles and longer claws, and may suffer from arthritis.

What You'll Learn
Examining the chicken's legs
Examining a chicken's legs is one of the most common ways to estimate its age. Young chickens have skinny legs, while older chickens have thicker legs. The legs of older chickens may also be more callused, worn, and rougher with some scales lifting slightly. The colour of a chicken's legs can also be an indicator of its age. Young chickens have pale beige legs, while older chickens have darker legs. However, the colour of a chicken's legs can change over time, and the legs will be fully coloured when the chicken is ready to mate.
Chicken spurs, which are small, sharp growths on the legs, can also indicate age. Young cockerels have short spurs, usually under 1 cm in length. By the time a cockerel is two years old, its spurs may reach 2.5–3 cm. While most hens do not grow spurs, some older hens may develop small ones.
It is important to note that determining a chicken's exact age by looking at its legs is not always accurate. The age of a chicken can vary depending on breed, individual factors, and environment. Additionally, factors such as lighting, molts, breed differences, and health conditions can impact the appearance of a chicken's legs, making it difficult to determine its age solely based on leg characteristics.

Looking at the spurs
The length of a rooster's spurs can indicate its age. A young cock will have short spurs, usually under 1 cm in length. By the time a rooster is two years old, its spurs may reach lengths of 2.5 cm to 3 cm. The growth rate of spurs is approximately 4 to 8 mm per year. Therefore, a rooster with spurs less than a third of an inch long at six months old is likely around a year old.
It is important to note that spurs can be maintained or removed, which may affect the accuracy of age determination. Additionally, some roosters may not develop spurs at all. While looking at the spurs can provide an estimate of a chicken's age, it should be considered in conjunction with other physical characteristics and behavioural indicators for a more comprehensive understanding of the bird's age.
To accurately determine the age of a rooster or cockerel using its spurs, the rings on the spurs can be examined. These rings represent the years of the chicken's life, allowing for a more precise age determination. However, this method relies on the presence of visible and distinct rings, which may not always be the case, especially in younger birds.

Checking the colouring
For hens specifically, observing their colouring can be an indicator of age. Before a hen starts to lay eggs, she will have all of her yellow colouring. Once she starts laying, "bleaching" will begin, and she will lose her colouring around her vent, eyes, and earlobes. After a couple of months of egg production, her beak will lose its colouring as well. The hen will lose her colouring in her shanks, feet, toes, and nails after six months of laying. When she stops laying, either for a moult or at the end of her productive life, the yellow colour will return in the same order it previously faded.
Additionally, the colour of a chicken's comb and wattles can provide some indication of its age. When chicks hatch, their combs and wattles are usually small, and the wattles may not be very noticeable. By week 12, the combs will be more apparent, and the wattles will be noticeable. Although neither the comb nor wattles will be vibrant, they will start to turn red. By the time a rooster is two years old, its spurs will be longer, reaching 2.5-3 cm in length.
While checking the colouring can provide some clues about a chicken's age, it is not always accurate, and other factors, such as behaviour and physical characteristics, should also be considered.

Counting the number of eggs laid
First Eggs
Hens typically start laying eggs between 18 and 25 weeks of age. So, if you have a pullet (a hen under one year old) that has just started laying eggs, you can estimate her age to be around five months old.
Egg-laying Frequency
In the first two years of their adult life, hens usually lay the most eggs. They may lay five to six eggs per week during this time. As they get older, the number of eggs laid will gradually decrease. For example, a Rhode Island Red hen that lays five to six eggs per week is likely one to two years old, while one that lays only one egg per week is probably several years old.
Egg Size
Young hens tend to lay smaller eggs, and as they mature, the egg size tends to increase. So, if a hen is laying extra small eggs, she is likely a young layer. However, it's important to compare the egg size to the typical size for that specific breed.
Molting Patterns
Observing molting patterns in conjunction with egg-laying habits can also provide clues about a chicken's age. For example, a hen that has gone through a molt in late summer or early fall is likely at least 18 months old, as this is when they start to prepare for the winter months.
While these guidelines can provide an estimate of a chicken's age based on the number of eggs laid, it is important to remember that each chicken is unique and may not follow these patterns exactly. Other factors, such as diet, health, and environment, can also influence egg-laying habits. Therefore, it is always best to consult with an experienced veterinarian or poultry expert if you need a more accurate assessment of your chicken's age.

Observing physical changes
Young birds are the easiest to identify. Chicks begin life with a short-lived fluffy yellow coating called 'down', which they wear for the first week or so of their lives. After this, small feathers begin to grow, and by the fourth week of life, they should have a complete set of feathers. At this stage, they will look a bit scruffy, like a bad haircut. The second and final mini-molt occurs around the seventh week, lasting until the twelfth week, when small baby feathers are replaced by the first adult plumage.
The boys will start to grow long pointed feathers on their necks, saddles, and tails, called hackle, saddle, and sickle feathers. Girls will grow feathers that are more rounded at the ends and uniform in length. By the twelfth week, a chicken will have put on a lot of weight, changing from a small fuzzy ball to a slender and somewhat gawky teenager.
From 16 to 20 weeks, adolescent chickens become totally independent from their mother hens. Pullets (females) will start to approach their point of lay, getting ready to lay their first eggs. This can take up to seven months for some breeds. Pullets are considered adults when they lay their first eggs, which occurs between 18 and 25 weeks. Male chickens, or cockerels, reach adulthood when they start to crow and show interest in hens, usually by chasing them, at around five months old.
Once they are adults, it is challenging to determine a chicken's exact age. However, some physical changes can provide clues. Roosters are identifiable by their spurs, which grow at 4 to 8 mm per year after their first year of life. By the time a rooster is two years old, its spurs may reach 2.5 to 3 cm in length. Hens that lay five to six eggs per week are likely in their first two years, as are cocks, as both will be in their prime with vibrant feather colours, smoother legs, and colourful combs and wattles.
As chickens continue to age, their combs and wattles will fade in colour and may become floppy. Their legs and beaks will also fade in colour, and their breasts will become firmer. Older chickens may have more callused and worn feet and legs, and their feathers may be missing, damaged, or include some bald spots.

Frequently asked questions
Young birds are the easiest to identify. Chicks have a fluffy yellow coating called down, which they wear for the first week or so of their lives. After that, they gradually molt and small feathers begin to grow. A baby chicken can be considered a chick until it sheds all its down, which usually takes around 12 weeks. Once a chick has molted and lost its down, it enters a transitional period, lasting until around 20 weeks old.
It is difficult to determine the exact age of an adult chicken. You can only make an educated guess based on their physical appearance and behaviour. For example, the number of eggs they lay in relation to other birds of the same breed, the size of the eggs, the condition of the vent, and the condition of the shanks (lower legs). Older hens will have coarser scales on their legs, and may develop wrinkles on their faces. Roosters will have longer spurs as they grow older.
Chickens will slow down egg-laying after their second year, and most hens that live to 5 years will no longer be laying. Older hens may also get longer claws as they are less active, and can suffer from arthritis, walking with a stiff leg or limp.
Hens over the age of 12 weeks are known as pullets, and this period usually lasts until they are 20 weeks old. Pullets are considered adults when they lay their first eggs, which occurs somewhere between 18 and 25 weeks. Male chickens reach adulthood when they start to crow and show an interest in hens, usually at around five months old.
