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. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in these areas with other birds and other vertebrates, particularly mammals. My overall conclusion is that chickens are just as cognitively, emotionally and socially complex 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.
家鸡属于鸟纲，而鸟纲一直是我们理解神经解剖学、认知和社会复杂性方面一场变革的焦点。现在已知至少某些鸟类在智力水平、情感复杂性和社会互动方面与许多哺乳动物不相上下。然而，这些新证据在很大程度上并未改变人们对鸡的看法。在本文中，我研究了关于鸡在认知、情感、个性和社会性前沿方面的同行评议科学数据，探索诸如自我意识、认知偏差、社会学习和自我控制等领域，并将它们在这些领域的能力与其他鸟类和其他脊椎动物，特别是哺乳动物进行比较。我的总体结论是，在许多方面，鸡在认知、情感和社会方面与大多数其他鸟类和哺乳动物一样复杂，并且需要对鸡进行进一步的非侵入性比较行为研究，以及重新构建当前关于它们智力的观点。
