The science behind poultry vision is an interesting one which has been under scrutiny for many years.
Current research tends to focus on light spectrums i.e. the colours hens see and how it affects natural behaviours.
The main goal is to assimilate natural daylight within the poultry house with an aim to improve flock performance and behaviour.
While a lot of the latest research can be confusing and complicated, it is worth being aware of the basics of poultry vision and the influence of lighting systems.
We have outlined some of the basic characteristics on the following pages.
Hens can move each eye independently and have a panoramic vision field of almost 300 degrees even without turning their head.
This panoramic view, alongside their binocular vision which allows them to focus on more than one object at once is what makes them so difficult to catch for example.
Their binocular vision is essential in the wild: as while the right eye is busy looking for food, the left is keeping a wary eye out for predators.
