Moreover, as with any taxonomic group, species-specific factors, such as evolutionary history and sensory abilities, need to be taken into account in order to interpret findings on cognition, emotion, sociality, and other characteristics and to make better informed comparisons across taxa.Therefore, what follows is a brief description of evolution, phylogeny, and domestication, as well as sensory systems, in chickens.).

In other studies, their welfare is ultimately related to productivity.

Far less numerous are studies of chickens on their own terms—as birds, within an evolutionary and comparative framework.

Rather, the answer may lie with the context in which we usually encounter them and how their use interacts with perceptions of their intelligence.

Unlike many other birds, chickens are categorized as a commodity, devoid of authenticity as a real animal with an evolutionary history and phylogenetic context.

When asked to rate the typicality of chickens as a member of the more general category of birds, raters usually give chickens a low score indicating that they are not considered typical birds (Malt and Smith ).

Therefore, even considerations of birds in general may not apply very well to chickens.A recent book on the behavioral biology of chickens by Nicol () is recommended for a much more comprehensive and wide-ranging description of studies of chicken cognition and behavior.The purpose of this paper is twofold: first, to gain a better understanding of the minds of chickens from the best scientific literature, separating fact from fiction; two, to identify compelling areas for future noninvasive research.

With over 19 billion worldwide, chickens are the most abundant of all domesticated animals (UN Food and Agricultural Organisation ), so this perception of chickens is not due to unfamiliarity with them per se.Likewise, the brains of birds have historically been viewed as simpler and more primitive than those of mammals.However, that assumption about avian brains has now been overturned by more recent studies showing that there are many functional similarities in the brains of birds and mammals, allowing for similar cognitive abilities.Now, more than ever, this simple realization has a special relevance because of the recent transformation in our scientific knowledge of birds in general.In the past few years, numerous studies have shown that there is no “bright line” between “avian” and “mammalian” intelligence and complexity; complex intelligence is found in both birds, mammals, and also fish (Brown ).
