Husband and wife team, Dan Joe and Margaret Kelleher began egg production in 1966 to supplement the farm income. They started with 700 hens in a barn at the home farm in Whites Cross on the outskirts of Cork city. Thanks to country markets, local shops, bakeries, and sheer hard work, the business grew year on year. The family have been involved in the development of the Irish egg industry- Margaret played an active role in The Irish Egg Association and her son D.J. is on the technical committee of Bord Bia which created the 'Egg Quality Assurance Scheme'.
