Organic
Hens producing organic eggs are always free range. In addition, hens must be fed an organically produced diet and ranged on organic land. Organic eggs are produced in the UK according to criteria set by the Advisory Committee on Organic Standards (ACOS) - which sets basic standards for organic production in the UK, in line with EU legislation.
There are a number of organic certification bodies that operate in the UK including the Soil Association, Organic Farmers and Growers and Organic Food Federation. However, the majority of organic eggs sold comply with the standards of Organic Farmers and Growers and Organic Food Federation. All adhere to ACOS' basic standards, but may introduce higher standards in certain areas for their members.
