Certain chicken breeds exhibit varying rates of growth due to their genetic characteristics. For instance, numerous meat-focused chicken breeds tend to experience rapid growth, whereas those specialized for egg production may have a slower development rate.

What Is The Average Time It Takes For A Chicken To Mature?

When a chicken reaches sexual maturity and starts to lay eggs, it is considered mature. This happens when the chicken is 16-24 weeks old. It can vary depending on breed, gene, and quality of feed.

Cornish Cross takes eight weeks to mature, while Australorp can take up to 24. Some chickens mature quicker than others. This is due to the differences in genetic code.

The Stages Of A Chicken’s Life

There are many phases to a chicken’s life. We will discuss the different stages of chicken life in this section.

Egg Development and Hatching

Hens usually lay eggs after 25 to 27 hours. This means they usually lay one egg per day. To lay fertilized eggs, hens do not need to mate with a list. They can store sperm in pouches within their sexual reproductive organs for up to 3 weeks.

Hens will lay eggs until they feel they have enough eggs. The hen will then continue to watch the eggs for 21 days before they hatch.

The egg will only need to take a brief break during this time to eat and drink water before returning to the nest to heat the eggs. The chicks will begin to absorb all the nutrients as soon as the egg hatches. This will provide them with enough energy to last for approximately 72 hours.

Chick Development

The mother will keep the chicks safe from cold and danger once the eggs are hatched. The mother will take care of the chicks for the first few days. By providing water and food, you can help the chicks.

If you’re incubating chicks, ensure they have water, warmth, and food. The chicks should be kept in a brooder for at least five days.

The chicks develop their correct features around five days old. At 12 days old, they will have a defined bone. The chicks will be 18 days old and have significant feathering. By day 30, they will be able to identify their breed.

The chicks will continue growing and learning all the skills necessary for adulthood, such as foraging, roosting, and foraging.

Adolescent

Adolescent chickens often appear smaller and thinner than adults. The juveniles should not be merged with the adults until they are at least 2/3 their adult weight. They can bully or even hurt older chickens if they are introduced too early. Therefore, it is a good idea to keep the adults and juveniles away from each other.

Chicken

Chickens are fully grown when they reach sexual maturity. Some chickens reach sexual maturity in as little as 18 weeks. Others take between 24 and 24 months.

When Do Chickens Lay Eggs?

When chickens reach sexual maturity, they lay eggs. When the yolk forms in the hen’s skin, the egg-laying process starts. Each egg takes 26 hours to develop and lay. The egg is laid once it has been incubated. This takes approximately 21 days.

Factors That Affect The Life Expectancy Of A Chicken

A backyard chicken can live for between 3-10 years. Many factors influence their lifespan.

Maladies

Despite all the efforts made to combat chicken disease, it is still a major killer of chickens. Certain diseases can be fatal and can lead to death if not treated promptly. It is essential to regularly inspect your flock to prevent the disease from entering your home.

To prevent them from contracting deadly diseases like lymphoid leucosis or mareks, it is important to vaccinate them regularly.

Lack Of Proper Housing

The role of chicken housing is vital in improving their health and wellbeing. Chicken coops protect birds from danger and keep them warm during winter and cool in summer.

The chickens can become more vulnerable to respiratory diseases if the chicken coop does not meet the required standards. This could reduce their lifespan. They are also easy prey for predators.

Surrounding Environment

How their kitchens are run plays a major role in their wellbeing and health. They will live longer if their kitchens are clean and provide adequate food.

However, their lifespan will be reduced if they live in filthy conditions with limited food.

Inadequacy Of Veterinary Care

Chickens, like all home-bred birds, need to be checked by a veterinarian regularly. Preventive medicine is always better than curative. Chickens will live longer if they are examined by a veterinarian regularly.

However, their chances of living a long life expectancy will decrease if a veterinarian doesn’t give them the proper attention.

Genetics

The reduction in chicken lifespan has been largely due to breed manipulation. Breed manipulation can cause genetic problems in the birds and, in some instances, may even reduce their lifespan. [1]
