I always heard brown were better too, but never knew why, so decided to look it up. This is all I could find:
You will find both white and brown eggs in the supermarket. What's the difference? White eggs are white, and brown eggs are brown, but that's it. One is no better for you than the other. They simply come from two different breeds of chickens. Brown eggs, however, are more expensive because the chickens that lay them eat more than those that lay white eggs.
Maybe someone else has a better explanation.....
Off to bed with this ole body.....
