Newly-hatched chickens have skills that require at least a few months or years for human babies to master, a new study has revealed.
Fields of intelligence ranging from structural engineering to self-control appear to come more naturally to chicks than toddlers, the Independent reported.
AdvertisementProfessor of animal welfare Christine Nichol, who reviewed 20 years of research on the topic for the University of Bristol, said we should no longer think of chickens as stupid.
In one test, the birds were allowed access to more food the longer they waited to start eating.
While 93 percent of hens were able to grasp this skill, comparable studies have suggested many humans cannot exhibit this kind of self-control until the age of four.
The study, supported by the Happy Egg Co., suggested that chicks are born with the ability to keep track of numbers up to five - preferring larger groups of eggs - a skill which babies need to be taught.
Chickens also reportedly have an instinctive ability to recognise structurally sound objects, favouring these over ones which seem dubious or inconsistent.
And they show awareness of objects which fall out of sight, keeping track of them in a way that is alien to babies up to the age of about one.
