ISA Brown
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.

What to Know Before Buying an ISA Brown
Finding a responsible ISA Brown breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells chickens commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.
Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the ISA Brown. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.
Use the search tool below to check whether any USDA-licensed facilities breeding ISA Browns appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
