Abstract

Modern layers descend from the red jungle fowl, a species with a highly diverse diet including fruits, seeds, herbage, insects and even small vertebrates [ 1] ( Figure 4.1 ). Despite over 8,000 years of domestication [ 2], there is no evidence that their exploratory and feeding habits have substantially changed.
