Chickens are often quickly dismissed as being not very intelligent, but given a chance, the humble chicken’s abilities will surprise you! Anyone who owns chickens will already know they have spectacular eyesight, able to catch the brief glimpse of the tiniest insect from meters away. But it is a common misconception that chickens are colorblind.
Chickens are not colorblind. Chickens have excellent color vision and can pick up on many spectrums of color, including violet and ultraviolet spectrums. This color vision helps them forage safely but is also thought to be important in mate selection and breeding.
There’s more than meets the eye when it comes to chicken vision. Not only can they see color well, but they can also see a lot more than we give them credit for. Keep reading to learn just how unique the chicken’s eye is.
Chickens Can See More Than Us
We, humans, are often human-centric when we compare the senses of animals. We often refer to animals who may view colors differently as colorblind, when in fact, they have evolved to view the world differently.
As far as chickens go, we can by no means call them colorblind. Chickens’ eyes contain all the cones (color sensing cells) that our human eyes do. In fact, they top us by having five types of cone cells, where we have a measly three. These extra cones allow chickens to see colors and tones we could not even imagine existing.
Some of these cones can detect violet and ultraviolet wavelengths, which are not visible to the human eye. Think of some human tools like black lights designed to expose differences in tone on the ultraviolet spectrum like what a chicken can visibly see.
In addition to this stellar color vision, chickens have extraordinary focusing abilities when viewing things both close and long distances. Chicken’s eyes possess two fovea—a pit in the eye that assists in focusing, meanwhile we only have one. One chicken fovea is for long-distance, while the other is for nearby.
Evolution of Chicken Colorvision
Chickens are decedent of dinosaurs. Make sense, right? Take your feathers, and you’ve got yourself a casting crew for the next Jurassic Park movie.
During the age where dinosaurs reigned the earth, mammal species all became nocturnal as they hid away from dinosaur predators. However, chicken ancestors roamed during the day, so now modern-day birds have a superior vision to most mammals due to million more years of vision evolution.
The double fovea in chickens’ eyes is an evolutionary trait for survival. The ability to focus on two things at once helps them watch out for predators and search for food nearby. This has dramatically increased their survival through their evolution.
The Use of Colorvision
These days our prehistoric feathered friends do not need to worry about such survival pressures of the wild. They get a comfortable life in a barn with ample space to roam around. So how does a chicken’s incredible color vision serve them now?

Final Thoughts: Never Underestimate a Chicken!
Chickens continue to surprise us. Their amazing biology and behaviors extend beyond their general view as being bird-brained and not very bright. A simple chicken has undergone millions of years of evolution to become the prime specimen with incredible vision.
Don’t underestimate the complicated and amazing vision of a chicken, they see things you could not even begin to imagine!
