When I first started raising chickens, one of the first questions I asked our veterinarian was, How long do chickens actually live? and Is there anything we can do to help them live longer, healthier lives?
As backyard chicken keeping becomes more popular, many people are finding that their hens and roosters quickly become more than just livestock—they become part of the family. And like any beloved pet, it’s only natural to wonder how much time you’ll have with them and how you can give them the best life possible.
The truth is, a chicken’s lifespan can vary quite a bit, depending on a few important factors like breed, environment, health care, and daily management. Knowing what affects their longevity can help you take steps to keep your flock healthier for years to come.
We’ll get into what you can expect when it comes to chicken lifespan, what shortens or extends it, and practical ways you can support your birds at every stage of their lives.
Nutrition Affects Lifespan
Just like with any living creature, a chicken’s diet plays a major role in its overall health and longevity. Thanks to better understanding and improved feed options, chickens today are no longer expected to survive on kitchen scraps or low-quality grains alone.
Modern chicken feeds are specially formulated to provide the right balance of nutrients and protein, helping keep your flock strong, healthy, and productive. There are even nutritious treats available for chickens, much like there are for cats and dogs.
That said, it’s important to avoid overfeeding. Too much food can lead to obesity, which brings its own set of health problems. To help your chickens live longer, aim for a balanced diet that supports their needs without going overboard.
Disease
Chickens are vulnerable to a variety of health issues, including parasites like worms, lice, and mites. Each one brings its own set of problems. Worm infestations can be especially serious and, if left untreated, can even be fatal. Lice cause irritation and damage to the skin and feathers, while mites feed on a chicken’s blood, which can lead to anemia.
The good news is that most of these issues are treatable with the help of a veterinarian. The sooner you spot a problem, the easier it is to treat successfully. That’s why it’s important to check over your chickens regularly—at least once a week. Look at their skin, inspect their feathers, and keep an eye on any changes in behavior.
Because chickens live outdoors, they’re naturally exposed to more risks. Mites and lice can come from wild animals that pass through your backyard, and worms are often spread through the droppings of other birds. While you can’t protect your flock from every threat, regular health checks give you the best chance of catching problems early.
In addition to parasites, chickens can also be affected by viral diseases, including certain strains of herpes and retroviruses. These illnesses are harder to predict and less understood, but once again, early detection and veterinary care offer the best chance for recovery.
Environment Influences Longevity
It will come as no surprise that a chicken that is kept in a clean, warm, and ambient environment will flourish more than one that has to live in poor conditions. As long as your chicken doesn’t have to suffer the stress of fending for themselves in a cold, damp, or similar environment, they will be able to live longer.
In addition to providing your chickens with the basics in their environment, it is also a good idea to ensure your yard is safe from predators or any larger animals that may inadvertently harm them. And if you have a coop or some form of housing, find the type that will keep them protected in all weather conditions.
You can buy coops that stay cool in summer and warm in winter, and this is exactly the kind you need to keep the health of your chickens optimal.
Medical Care
You may think that if your chicken needs medical attention, you can just drive to your local vet, but unfortunately, this is not always the case. While vets are highly trained in the treatment of most animals, it doesn’t include all animals, and you might struggle to find one who can efficiently deal with poultry.
Since keeping chickens and other poultry has become more common, many veterinarians are now improving their knowledge and skills to assist when needed. However, it is always best to find a veterinarian who has specific expertise in caring for birds and poultry, ensuring you receive the distinct care required for your chickens.
Genetics
There is a well-documented history of manipulated breeding in poultry; hybrids are created to maximize egg-laying abilities, but this can, in turn, lead to health problems. When you rescue or adopt your chicken(s) you may not be aware of its genetic history, but if the place where you are getting them from can tell you, this will be able to set your expectations with life expectancy.
There is a good chance that your chicken(s) doesn’t have a poor genetic history, but if they do, then you can expect your chicken(s) not to live as long as one whose history doesn’t include manipulation or inbreeding.
Overall, if we take an average, you can expect a well-cared female chicken to have a lifespan of between eight and ten years, and a male to have a lifespan of between five and eight years.
Although the world record for the lifespan of a chicken currently stands at sixteen years, if you are fortunate enough, you can spend a great number of years with your backyard family.
What Is The Average Lifespan Of A Laying Hen?
The average lifespan of a laying hen is estimated to be between eight and ten years. Because numerous environmental, medical, and nutritional factors are involved, it is challenging for anyone to provide a definitive answer.
But eight to ten is the general rule if the hen is kept in good condition, with a healthy diet, and can receive medical care when necessary.
Even though a laying hen can live to be as old as ten, or even longer, they won’t lay eggs for this many years. At around six months old, the hen will start laying eggs and will continue to do so until around five to seven years old. Although towards the end of their laying years, egg frequency will decrease a lo,t and is perfectly normal.
I am sure you have come here looking for a specific number, but ultimately, it is impossible to say for sure. With chickens, numerous factors influence their lifespan, including living conditions, diet, disease, genetics, and medical care (see the top of the article for an in-depth examination of each factor).
If we consider the average lifespan, backyard chickens can live anywhere from five to ten years, although the current record for the oldest chicken stands at sixteen years.
So, your backyard chickens can surpass the average age and live long, fruitful lives with you. But, of course, being in the safety and comfort of your backyard will give them the best chance possible at living for an extended period.
How Can You Tell How Old A Chicken Is?
If the place where you have obtained your chicken isn’t able to tell you the age of the chicken, then you must be able to make an educated guess. Knowing a chicken’s age is essential to know what diet to feed them, what care they need, and even to see the frequency of eggs you can expect and, therefore, ascertain if there is a problem.
Estimating the age of your chicken isn’t always easy; there is no exact science behind it, and if you are really unsure, it may be worth consulting a veterinarian for advice. However, the basics of what to look out for to determine age are outlined below.
| Age Range | Developmental Milestones |
|---|---|
| Zero to One Week | Featherless, tiny, and immobile chicks. |
| One to Six Weeks | Male feathers become colourful, and the rooster’s tail forms. Females’ pelvic bones widen slightly. |
| Four to Six Months | Chicks reach full maturity. Females start egg-laying, and males develop leg spurs. |
| Six Months to 2 Years | Male feathers become colourful, and rooster tail forms. Females’ pelvic bones widen slightly. |
| Three to Four Years | Decreased egg production, larger eggs. Males become calmer and less active. |
| Five Years Plus | Rare egg-laying, chickens enter old age. Rougher and bigger scales on feet, decreased feather colors, weakened beaks, and declining overall health. |
Zero To One Week
Of course, at this stage, it will be evident that the chick is this young, as well as being tiny and barely able to move, they will also be featherless.
One To Six Weeks
During this period, the feathers will start to grow in, and after six weeks, the process should be complete. This is also the period when you can determine the sex of your chicken. The male’s comb will be far redder than a female’s, and male chickens will often be taller at this point.
Four To Six Months
Over this month, a male’s feathers will become very colourful and the infamous rooster tail will be clear. For females, their pelvic bones will start to become wider, but this usually does not occur to the extent necessary for egg-laying.
Six Months To 2 Years
At this age, all chickens now look fully mature, and they are officially adults.
A female’s pelvic bones are now wide enough, and the egg-laying process will begin. You can expect to lay around one egg per day for the first couple of years.
For males, you will notice spurs on the back of their legs; the length of these spurs will increase with age, reaching approximately an inch long by the time they are two years old.
Three To Four Years
By this stage, hens will lay eggs less frequently, but their eggs will be larger than usual. The size of the eggs is a reliable indicator of age in female chickens. Males will start to quiet down at this point, as their hormones aren’t as strong, and they won’t grow or mate as much as they did before.
Five Years Plus
At this point, hens will rarely lay eggs, and a rooster will be very quiet and slow. Most chickens can only expect to live for a couple more years after this, so they are effectively old. You will also notice that a chicken’s scales on its feet will become rougher and bigger with age. Feather colours may decrease, along with beak strength, and overall health will start to deteriorate.
Do Chickens Die Of Old Age?
Yes! Although it may sometimes seem like there are a hundred different factors that may end a chicken’s life too soon, chickens do indeed die of old age.
If your chickens have reached a point of old age, then you should take comfort in knowing that, because of you, they were able to have the most extended life possible.
Why Do Old Chickens Die?
Old chickens die for the same reasons that any animal or even person dies of old age: their body is weak, and they no longer have the strength to go on; they have lived their life, and it is time to let go. If your chicken dies of old age, you will notice that it is losing weight and becoming increasingly lethargic in its movements.
Unfortunately, when this happens, there isn’t anything you can do other than let nature take its course. A chicken dying of old age will eventually pass peacefully in its sleep.
When To Cull Hens?
The process of culling hens means removing any that are sick, injured, or inferior in some way. And if possible, you should do it as regularly as needed. As awful as it might feel, if you leave hens that are sick, this could put your whole flock at risk and you could end up with a lot of dick chickens rather than just one.
Culling hens also means there is more space for the others, as well as more food and water available.
The timing of when to cull hens can vary depending on the specific situation.
Hens that are sick, injured, or significantly inferior should be culled as soon as their condition is identified. Similarly, if you are raising hens for egg production, non-productive hens that rarely lay eggs can be culled to optimize resources for the productive ones.
It is essential to regularly assess the health and productivity of your flock and make culling decisions accordingly.
If you are raising hens for egg production, then culling the hens that don’t lay eggs, or lay eggs very infrequently, means there are more resources available for the hens that lay eggs regularly.
Culling hens is essential to keep the flock safe and in tip-top shape.
As much as you wish it, you cannot make chickens live forever, but with the proper care and environment, you can undoubtedly help your backyard chickens have the kind of life they deserve.
