Abstract

Determining the age of bird remains after the cessation of growth is challenging due to the absence of techniques such as tooth eruption and wear available for mammals. Without these techniques it is difficult to reconstruct hunting strategies, husbandry regimes and wider human‐animal relationships. This paper presents a new method, developed from a collection (n = 71) of known‐age specimens of domestic fowl (Gallus gallus domesticus L. 1758), for assessing age based on the fusion and size of the tarsometatarsal spur. Using this method we reconstruct the demographics of domestic fowl from Iron Age to Early Modern sites in Britain to reveal the changing dynamics of human‐domestic fowl relationships. We highlight the advanced age that cockerels often attained in their early history and how their life expectancies have subsequently declined.
