History
ISA stands for Institut de Sélection Animale, the company which developed the hybrid in 1978 for egg production as a battery hen. In 1997, the ISA Group merged with Merck & Co., forming Hubbard ISA, so the hybrid is sometimes called Hubbard Isa Brown. In 2005, Institut de Sélection Animale (ISA) and Hendrix Poultry Breeders (HPB) merged in ISA B.V., which also became part of the multi-species breeding company, Hendrix Genetics. In March 2005, Hubbard was purchased from Merial Ltd by Group Grimaud La Corbiere, SA.
