Here are few thoughts to change your perception of chickens:
- Chickens possess a number of visual and spatial capacities, arguably dependent upon mental representation, such as some aspects of stage four object permanence and illusory contours, on a par with other birds and mammals.
- Chickens possess some understanding of numerosity and share some very basic arithmetic capacities with other animals.
- Chickens can demonstrate self-control and self-assessment, and these capacities may indicate self-awareness.
- Chickens communicate in complex ways, including through referential communication, which may depend upon some level of self-awareness and the ability to take the perspective of another animal. This capacity, if present in chickens, would be shared with other highly intelligent and social species, including primates.
- Chickens have the capacity to reason and make logical inferences. For example, chickens are capable of simple forms of transitive inference, a capability that humans develop at approximately the age of seven.
- Chickens perceive time intervals and may be able to anticipate future events.
- Chickens are behaviourally sophisticated, discriminating among individuals, exhibiting Machiavellian-like social interactions, and learning socially in complex ways that are similar to humans.
- Chickens have complex negative and positive emotions, as well as a shared psychology with humans and other ethologically complex animals. They exhibit emotional contagion and some evidence for empathy.
- Chickens have distinct personalities, just like all animals who are cognitively, emotionally, and behaviourally complex individuals.
