Several recent studies have shown that chickens are bright animals that are able to solve complex problems, demonstrate self-control and worry about the future. Chickens are smarter than cats and dogs and even do some things that have not yet been seen in mammals other than primates. Dr. Chris Evans, who studies animal behavior and communication at Macquarie University in Australia, says, “As a trick at conferences, I sometimes list these attributes, without mentioning chickens and people think I’m talking about monkeys.”
