What Is the ISA Brown Chicken?
The ISA Brown is a hybrid chicken specifically bred for the poultry industry. It excels in egg production, laying over 300 eggs per year. It’s also known for its friendly and adaptable nature, making it a top choice for both backyard poultry keepers and commercial egg producers.

ISA Brown Chicken Origin and History
Developed in 1978, the ISA Brown is a relatively new breed of chicken. Originating in France, ISA stands for Institut de Sélection Animale, the institute responsible for its development.
This breed is the product of meticulous breeding efforts aimed at meeting the demands of commercial egg production, combining traits like high egg yield and docility.
The exact genetic makeup of the ISA Brown is a closely guarded trade secret. It is said, however, that the breed originated from extensive breeding involving Rhode Island Red and White breeds and the White Leghorn.
Known for its impressive food-to-egg conversion ratio, the ISA Brown quickly became well-known outside of France.
Today, the breed’s ability to lay eggs consistently and its beginner-friendly nature continue to make it a popular choice for both backyard flocks and larger poultry operations.
Its origin and development showcase the advancements in selective breeding in the poultry industry.
ISA Brown Chicken Appearance
Since ISA Brown chickens are hybrids, their appearance can vary because there is no official breed standard for them. To a casual observer, ISA Browns look like any other brown chicken.
With their rich chestnut brown color, these chickens blend seamlessly with other brown chicken breeds, often leading to delightful mix-ups.
In fact, many people commonly mistake them for Comets, Rhode Island Reds, and Red Star Chickens due to their similar appearance.
However, a trait that makes them special is that they are sex-linked. This allows keepers to determine their sex by the color of their feathers when they hatch.
The hens exhibit a consistent chestnut brown color from head to tail, while the roosters are typically brown with white plumage from the chest down.
Moreover, roosters have larger and redder wattles and combs compared to the hens, and these features become more pronounced as the chicks age.
Despite their resemblance to other breeds, ISA Browns hold their own charm. Their upright, short tails, reddish-orange eyes, and occasional white tail feathers add to their distinctive yet familiar presence in the coop.
ISA Brown Chicken Size and Weight
Known for their modest size, ISA Brown chickens fit well in various poultry settings.
The hens of this breed are typically medium-sized, with an average weight of about 5 pounds. Meanwhile, the roosters are slightly heavier, weighing around 6 pounds.
This difference in weight between the genders is common in many chicken breeds and is noticeable as they mature, helping keepers distinguish between the genders.
Despite not being large enough to be ideal for meat production, ISA browns’ size and weight make them a versatile choice for chicken keepers, whether in backyard flocks or larger operations.
Because of their versatility, they are a good option for people looking to strike a balance between manageable size and egg production.
ISA Brown Chicken Temperament and Behavior
ISA Brown chickens are beloved for their docile nature and friendly behavior, making them a delightful addition to any backyard coop.
They are known to be non-aggressive, which makes them family-friendly and suitable for homes with children. Whether free-ranging or perching in the chicken coop, they exhibit a calm and approachable nature.
This breed’s approachable character means they often seek attention, adding a touch of warmth and liveliness to any coop.
Moreover, they tend to form close bonds with their keepers and get along well with different breeds in the flock thanks to their gentle disposition. For this reason, they are usually recommended for first-time chicken owners.
The ISA Brown’s temperament guarantees that they are a pleasure to have around, regardless of your experience level with chicken ownership.
Their affectionate nature ensures they’re not just seen as egg producers but also as cherished pets.
Egg Production and Broodiness of the ISA Brown Chicken
ISA Brown chickens are one of the best-laying hens in the world. An ISA Brown hen can lay around 300 to 350 large brown eggs per year, with an average of six eggs a week.
They typically reach the point of lay around 20 to 22 weeks of age, which is earlier than several breeds. This prolific egg-laying ability makes them an excellent choice for those seeking a steady supply of fresh eggs.
However, it’s important to note that ISA Browns’ peak egg production only lasts for around two years. After that, their egg-laying rate may decrease, but they continue to be a valuable addition to any flock.
In contrast to their egg-laying prowess, ISA Browns rarely go broody. This trait ensures they lay lots of eggs without interruptions, as laying hens are less likely to sit on their eggs to hatch them.
Noise Levels of ISA Brown Chickens
The ISA Brown is one of the more calm and less flighty chicken breeds, making it a popular choice for backyard chickens.
In my extensive travels and interactions with various chicken breeds, I’ve observed that ISA Browns are generally quieter. Their gentle nature seems to contribute to their lower noise levels than other more active breeds.
While they had their moments of vocalization, especially during egg-laying, they were less disruptive overall.
This trait made me appreciate ISA Browns even more, and I would highly recommend them to anyone who wants productive chickens but lives in an area where noise might be a problem.
How to Take Care of Your ISA Browns
Taking care of ISA Brown chickens requires a thoughtful approach to meet their unique needs.
With proper nutrition, a comfortable coop, and regular attention, you can ensure these hardy and productive layers will thrive under your care.
Lifespan and Health Issues
ISA Brown chickens are known for their hardiness and prolific egg-laying abilities. However, this impressive productivity comes at a cost to their lifespan.
Their constant egg production without significant breaks takes a toll on their bodies over time.
Because of this, ISA Browns have a relatively short lifespan, typically ranging from 2 to 3 years, although some can live up to 5 to 8 years with proper care.
Moreover, they are prone to reproductive issues such as egg yolk peritonitis, cancer, and egg prolapses, especially after two years of age. Thus, regular health checks are vital to ensure they remain in optimal condition.
Further, ISA Browns are not recommended for breeding as they won’t breed true, and their offspring may have poor health.
Despite their shorter lifespan compared to some other breeds, with TLC, ISA Browns can thrive and contribute greatly to any flock.
Properly feeding ISA Brown chickens is crucial for their health and egg production. Since these chooks are capable of producing eggs at a rapid rate, they have particularly high dietary needs.
Providing them with a high-quality layer feed containing at least 17% protein is recommended to maintain egg quality and quantity, although 16% protein will do.
Additionally, supplementing their diet with calcium sources, such as oyster shells, is essential for strong eggshells. Regular access to clean water is equally important.
By meeting their feed and water needs and providing occasional treats like fresh vegetables, you can maintain their health and ensure they remain a thriving and productive part of your backyard flock.
Coop Setup and Roaming
Setting up a comfortable coop is essential for ISA Brown chickens. Make sure that each chicken has at least 4 square feet of coop space to prevent antisocial behaviors like feather pecking.
However, more coop space is ideal if you do not let them free range. Even though ISA Browns prefer to be around their coop, they do love having access to free-range areas where they can roam and forage.
Moreover, for ISA Brown hens, a well-designed coop should have enough perch area and nesting boxes.
Each chicken requires an average of 8 to 10 inches of perch space, and offering a variety of heights allows them to choose their preferred roosting spot.
In terms of nesting boxes, a standard 12×12 inch box should be plenty for their needs.
To further improve their overall comfort and hygiene, adding a dust bath area is also beneficial as it helps them keep their feathers healthy and control parasites.
ISA Brown chickens are adaptable to various climates, but it’s essential to monitor their environment.
These chickens can withstand winter temperatures at or slightly below 32°F, but they should not be exposed to freezing temperatures for prolonged periods.
They also fare well in hotter climates, but providing them with shade and ample water is crucial to prevent overheating.
Ensuring the coop is well-insulated during winter and well-ventilated during summer will help maintain a comfortable temperature for these chickens.
How Much Does an ISA Brown Chicken Cost?
The cost of an ISA Brown chicken can vary, but they are generally affordable, making them accessible for many chicken keepers.
Prices can range from around $3 to $5 per chick, depending on whether you purchase pullets, cockerels, or straight-run chicks. It’s advisable to check with different sellers for the most competitive prices and availability.
ISA Brown chicks can be purchased from various hatcheries and poultry suppliers, both online and locally.
These websites provide detailed information on the chickens, ensuring buyers are well-informed about the health and condition of the birds.
For those not comfortable purchasing online, you can check the hatcheries’ websites to see if they are located nearby.
If so, a visit can be arranged to personally select and purchase the chickens, allowing you to assess the birds’ condition and gather relevant information directly.
