In 2008, all Cobb line birds made up around 30-40% of global broilers. [10] In 2016, the Cobb 500 alone was nearly 50%. [3] More broadly, fast-growing chickens now make up the vast majority of the global chicken supply. As of 2021, 90% of the global broiler population is part of either the Cobb or Ross lines, which are both fast-growing. [11]
Broiler chicks. The broiler industry is the process by which broiler chickens are reared and prepared for meat consumption. Worldwide, in 2005 production was 71,851,000 tonnes. From 1985 to 2005, the broiler industry grew by 158%. [1] A key measure of performance is the feed conversion ratio (FCR), the ability to convert feed into edible product.
Breed broiler is any chicken (Gallus gallus domesticus) that is bred and raised specifically for meat production. [1] Most commercial broilers reach slaughter weight between four [2] and six weeks of age, although slower growing breeds reach slaughter weight at approximately 14 weeks of age. Typical broilers have white feathers and yellowish skin.
In the first week of a broiler's life, it can grow up to 300 percent of its body size. A nine-week-old broiler averages over 9 pounds (4 kg) in body weight. At nine weeks, a hen will average around 7 pounds (3.2 kg) and a rooster will weigh around 12 pounds (5.5 kg), having a nine-pound (4 kg) average. Broilers are not raised in cages.

One indication of the effect of broilers' rapid growth rate on welfare is a comparison of the usual mortality rate for standard broiler chickens (1% per week) with that for slower-growing broiler chickens (0.25% per week) and with young laying hens (0.14% per week); the mortality rate of the fast-growing broilers is seven times the rate of ...
