Observations

Chickens are considered a relatively short-lived and fast ageing species [0136]. The maximum longevity in captivity of these birds, however, has been reported to be 30 years [0001]. This is not impossible considering the large number of animals kept in captivity, yet remains unproven. For comparative analyses the use of a more conservative value for maximum longevity, such as 15 or 20 years, is recommended. Domestic chicken reach sexual maturity before six months of age.
