Figure 4.

Limb bones (femur, tibiotarsus, tarsometatarsus) of a modern broiler and a red jungle fowl. A juvenile broiler and red jungle fowl silhouette with limb bones are shown at proportionate size to each other for comparison. Broiler limb bones (left): male, five weeks of age and a Cobb, specimen R650, from the School of Archaeology and Ancient History, University of Leicester. Cross-bred red jungle fowl limb bones (right): male, six weeks of age and of modern breeding stock from an ancestral line, specimen NHMUK S/2009.1.11, from the Ashdown Collection, Natural History Museum, Tring. At slaughter age the over-sized but immature skeleton of the broiler is characteristically poorly ossified and relatively featureless.
