Why Are Some Eggs Brown and Some Eggs White?

There is more than one kind of chicken.  Some have white feathers and others have red or brown feathers.  The white chickens lay white eggs.  The red or brown chickens lay brown eggs.  Brown eggs often cost more because the red and brown chickens eat more food than the white chickens. 

Which color of egg do you like more?  Which color of chicken do you prefer?

Compare one brown egg with one white egg.  Do they weigh the same?  Does one cook faster?  Do you notice a difference in flavor?  The food the chickens are fed will affect the taste too.
