The ISA Brown is a crossbreed of chicken, with sex-linked coloration. It is thought to have been the result of a complex series of crosses including but not limited to Rhode Island Reds and Rhode Island Whites, and contains genes from a wide range of breeds, the list of which is a closely guarded secret. It is known for its high egg production of approximately 300 eggs per hen in the first year of laying.
ISA Browns are typically raised in controlled environments, such as commercial egg farms or backyard coops. They thrive in a range of climates, but require protection from extreme weather. Adequate shelter and access to free-ranging areas or runs is recommended to ensure their well-being.

The ISA Brown is renowned for its prolific egg-laying capabilities, making it a popular choice for both commercial egg production and backyard flocks. Its friendly and calm nature makes it easy to manage, although it is primarily bred for productivity rather than exhibition. This breed does not breed true, meaning its offspring may not exhibit the same characteristics as the parent birds.
