The ISA Brown is a hybrid type of Sex Link chicken, which is the result of crossing Rhode Island Reds and Rhode Island Whites.[1] The ISA Brown is a hybrid, not a true breed. It is known for its high egg production of approximately 300 eggs per hen in the first year.
[edit] History
ISA stands for Institut de Sélection Animale, the company which developed the breed in 1978 for egg production as a battery hen. In 1997, the ISA Group merged with Merck & Co., forming Hubbard ISA, so the breed is sometimes called Hubbard Isa Brown. In 2005, Institut de Sélection Animale (ISA) and Hendrix Poultry Breeders (HPB) merged. Institut de Sélection Animale SAS, France (ISA SAS) is now an operational centre of Hendrix Genetics. In March 2005, Hubbard was purchased from Merial Ltd by Group Grimaud La Corbiere, SA.

The Hubbard Isa Browns hold about 60% of the World Brown Egg Market.
All other egg laying breeds are judged and compared to these. They offer you exceptional egg output,
resulting in low feed conversion. Bred for large egg size, the in-built adaptability allows you
to produce an average egg size from 62 to 65 grams or so.Isa Browns have a current livability
of 97.3% and hen housed average production to 76 weeks is 321 eggs. Average egg weight is 62.8 g.
Personal note:
I have had production reds and New Hampshire production birds (from hatcheries). I have a friend that has ISA browns. They look just like sexlinks, and they lay the nicest, biggest , brown eggs you ever saw. If I were wanting to purchase a breed for egg production, I would get some of these outstanding birds. I believe they came from a hatchery in MO.
