OMG Facts - Feeding hens certain dyes, their egg yolk color changes. Green eggs and ham, anyone?

 The Color of a chicken egg's yolk is dependent on the diet of the hen that lays the egg. Certain kinds of corn can make the yolk look more orange or yellow, and peppers can make the yolk look red. In the US, people expect their egg yolks to be lighter, but in parts of Europe, people expect the yolks to look more of a darker yellow.

If the yolks can't become yellow naturally through the hen's diet, farmers may use synthetic dies to change the color.
