The popular Isa Brown
At De Meidoornhoeve, we welcome you to discover our beautiful Isa Brown laying hens. These warm red ladies with white tails are the most widely kept laying hens in the world, and that is no coincidence. With a friendly character, exceptional egg production, and remarkable adaptability, this chicken is a favorite for both beginners and experienced poultry keepers.
Origin of the Isa Brown
The Isa Brown is a hybrid laying hen developed in 1978 by the French company Institut de Sélection Animale, hence the name ISA. The chicken originates from a deliberate cross between the Rhode Island Red and the Rhode Island White, two American breeds that each brought their own qualities: productivity, robustness, and a calm temperament.
Nearly half a century after her introduction, she remains the most popular laying hen worldwide. She is kept in both commercial poultry farms and private backyards, a testament to her versatility. Along with the Harco and the Bleu de Lande, she belongs to the modern hybrid layers, bred for optimal production and easy maintenance.
Top production of large brown eggs
This laying hen was bred exclusively with one goal in mind: maximum egg production. And she does so with impressive consistency. She lays up to 280 to 320 large brown eggs per year, averaging 6 eggs per week during the peak season. This makes her one of the most productive laying hens in the world.
What makes her special: she starts laying very early, around 18 to 20 weeks old. With other breeds, this can take up to 26 weeks or more. Furthermore, she continues to lay steadily through the winter months, albeit slightly less than in the height of spring.
A frequently asked question is: what is the difference between an Isa Brown and a Lohmann Brown? Both are hybrid layers with similar production numbers (~300 eggs per year). The difference lies subtly in origin (Isa = French, Lohmann = German), appearance (Isa has a white tail, Lohmann is a more uniform brown), and character (Isa is considered slightly more curious and affectionate). For most hobby keepers, the practical difference is minimal.

Characteristics
The Isa Brown is a medium-sized chicken weighing around 2 to 2.5 kg, with a striking warm red to chestnut brown plumage. Her recognizable white-colored tail makes her easy to distinguish from other brown laying hens. She has a pink beak, an upright red comb, and red wattles.
A small detail that makes the difference: not every “brown laying hen” is an Isa Brown. An Isa Brown has a white tail, while other brown hybrids like the Redco have a black tail. Once you know the difference, an Isa Brown is instantly recognizable.
Beginner favorite and affectionate companion
The Isa Brown is perhaps the most beginner-friendly laying hen in existence. She is curious, social, easy for children to approach, and adapts quickly to a new environment. Tension in the chicken run is rare, and she combines perfectly with other calm breeds such as the Sussex, the cuckoo-colored laying hen, or the Bleu de Lande.
On top of that, she is hardy and low-maintenance: a dry and well-ventilated chicken coop, plenty of space to forage, and high-quality feed are enough for a happy chicken life.
One important note: like all high-production hybrid laying hens, the Isa Brown has a shorter peak production period. For the first 2 years, she lays almost daily, after which production decreases. This is a trait common to every modern hybrid, including the Harco or Bleu de Lande. For those who want purebred chickens that continue to lay at a slower pace for years, a Sussex can be a great alternative.

How many eggs does an Isa Brown lay per year?

An adult Isa Brown hen weighs between 2 and 2.5 kg. This makes her a medium-sized chicken, comparable in size to the common brown laying hen.
Where does the name "Isa" come from?
“Isa” refers to the French company Institut de Sélection Animale, which developed this breed in 1978. It is not a diminutive, but an abbreviation of the breeding organization.
What is the difference between an Isa Brown and a Lohmann Brown?
Both are popular brown hybrid laying hens with similar production numbers (+/- 300 eggs per year). The Isa Brown comes from France and has a distinctive white tail, while the Lohmann Brown comes from Germany and is more uniformly brown in color. In terms of character, the Isa Brown is often described as slightly more curious and affectionate.
How long does an Isa Brown keep laying eggs?
