Science news. From Fox News. Seriously. The article discusses how the cones are arranged within the eye of a chicken. Humans have 3 cones, so we see 3 colors, and the combinations of those. Chickens have 5 cones. The article says one type is for detecting light levels, but even so, they see many more colors than we do. But not as many as the mantis shrimp. Best creature ever.
