Which of the following farm animals is tetrachromatic, meaning it can see four light wavelengths, including red, blue, green, and ultraviolet?

Chickens have amazing vision. In addition to having the basic color cones that humans do (red, yellow and blue), they also have an ultraviolet light cone. Seeing UV light allows chickens to more easily find shiny bugs, seeds, berries, and fruits, pecking with the utmost precision.
