Why Do Chickens Eyelids Go Up? Uncovering the Mystery of Chicken Eyes
Have you ever wondered why chickens have such unique eyelids?
Unlike humans, who only have one set of upper and lower eyelashes to protect their eyes from debris and dust, chickens have two sets of eyelids!
The inner lid is called the palpebra tertia, while the outer layer is known as the palpebra bulbi.
These specialized lids help keep dirt out of a chicken’s eye while allowing them to see clearly in all directions.
But what about when they suddenly lift up off their face? Why do chickens eyelids go up like that? Let’s take a closer look at this fascinating phenomenon…
The Mystery of Why Do Chickens Eyelids Go Up:
One popular theory suggests that chickens raise their eyelids to increase their field of vision when they are startled or threatened by predators.
This makes sense since it allows them to quickly scan their surroundings for danger without having to move their head too much. However, research has shown that there may be more to it than just that.
Some experts believe that chickens also use their eyelid movements as a way to communicate with each other. For example, they might flicker their eyelids rapidly to signal aggression towards another bird or flatten them against their eyes to show submission.
It’s possible that these subtle cues play an important role in social interactions within a flock.
How Many Eyelids do Chickens Have?:
As we mentioned earlier, chickens actually have two sets of eyelids – the palpebra tertia and the palpebra bulbi.
The palpebra tertia is located on the inside of the eye and is made up of smooth muscle fibers that can contract and relax to control the amount of light entering the eye.

The palpebra bulbi, on the other hand, is the external layer of skin that covers the entire surface of the eye.
It contains feathers and scales that provide protection against injury and UV radiation. Together, these two layers work together to protect and support the delicate structures of the chicken’s eye.
What Color Do Chickens See and Do They Have Night Vision?:
Chickens have excellent color vision during daylight hours thanks to special photoreceptor cells in their retina called cones.
These cones allow chickens to distinguish between different colors and shades, which helps them find food and identify potential mates. At night, however, things get a bit trickier.
While chickens don’t have true “night vision” like some nocturnal animals, they still rely on their rods – another type of photoreceptor cell that is sensitive to low levels of light. With these rods, chickens can navigate around their coop and yard even in dimly lit conditions.
What Colors do Chickens Avoid and are Most Attracted To?:
Interestingly enough, studies have shown that chickens prefer certain colors over others.
In general, they tend to avoid bright reds and yellows but are drawn to blues and purples.
One study found that chickens were able to recognize and respond to specific wavelengths of blue and violet light, suggesting that they may be particularly attuned to those hues.
So if you want to attract your backyard chickens, try incorporating lots of blue and purple flowers into your garden design!
