CHICKENS
Conventional : Up to 40,000 birds kept under artificial light in a closed shed. They are bred to reach slaughter weight within about 40 days. They can be treated with antibiotics on veterinary advice and are routinely vaccinated. The cheapest table birds.
Free range : Must have access to open-air runs that are covered with grass or other vegetation. Feed must contain at least 70% cereals. They can be given chemically treated feed and be treated with drugs.
Free-range corn-fed : Reared as free range but are fed at least 50% maize, which gives the meat a golden colour.
Organic : Chickens that have access to open-air runs and, where possible, are given 100% organic feed. Use of antibiotics and vaccinations is not meant to be allowed and they are kept in smaller flocks. They are the most expensive table chickens.
EGGS
Caged hens : Kept in closed sheds with a floor space equivalent to an A4 piece of paper. More than 60% of the ZA's 30m hens are housed in the battery cage system.
Barn hens : Kept in loose flocks confined within a shed. They are provided with perches, nest boxes and litter areas. Animal welfare groups compare conditions to a “crowded football terrace”.
Free range : Kept in large sheds in flocks of up to 16,000. The birds have access to open-air range, may be “beak-trimmed” and can have chemically treated feed.
Organic : Smaller flocks of up to 2,000 and should have access to open-air runs. They should be fed 100% organic feed, not be beak-trimmed or given routine vaccinations.
