Abstract

Original Abstract: Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. Some birds are now known to be on a par with many mammals in their intelligence, emotional sophistication, and social interaction. Yet views of chickens have largely remained unrevised in light of this new evidence. In this paper, I examine the data on cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities with other birds and other vertebrates, particularly mammals. My overall conclusion is that chickens are just as complex cognitively, emotionally and socially as most other birds and mammals in many areas, and that there is a need for further noninvasive comparative behavioral research with chickens as well as a re-framing of current views about their intelligence.
