We saw an ad the other day which stated that their chickens were fed a diet of corn and Marigolds.  Now, while I could understand the corn, the Marigolds remained a mystery.  So, I did some research.

It seems that when chickens are fed Marigolds, their skins develops a yellow hue.  And a yellow chicken is preferred by consumers over a white one.  So, the chickens are fed Marigolds.  And, I have to admit that a yellow chicken is much more appealing than a plan white one.

I wonder if the chickens would turn red if you fed them beets?
