Fishy egg odour gene eradicated in ISA Warrens
Hatchery business Joice and Hill has announced that TMA (Tri-Methylamine) has been eradicated from all ISA Warren parent stock delivered to the UK in the past 12 months.
TMA is a gene that causes a fishy odour in eggs. Joice and Hill and parent company Hendrix has gradually been breeding the gene out of all of its chicks, and ISA Warrens are the last of their “big four” breeds to have the gene eradicated.
Stephen Turner, technical director at Joice and Hill said: “The investment and commitment required to eradicate TMA from a breed is considerable and is reflection of the importance of the ISA Warren to the free range sector in the UK.”

The ISA Warren now offers free range farmers across the UK a bird that Hendrix Genetics back as being TMA free and is supported in the field by Joice and Hill.
Joice and Hill has also hatched the first Shaver Browns since ISA announced changes to the UK distribution set up last December
The Shaver Brown is extremely popular in the UK, where it has a strong traditional following and is well regarded for its versatility and egg colour, says the company.
