The color of the egg is based soley on the breed of the chicken, not the feed being given to them. Also, there is NO difference nutritionally or otherwise in white and brown eggs.
Bingo Lindseyup67 you win the prize. Must have a farmer background.
It is all in the breed of the chicken and the assembly line, egg layers.
Hens are bred to mass produce, with a ratio of eggs, to feed poundage. Generally, brown egg layers are not as prolific as white egg layers, thus the premium.
If you get eggs with very pale yokes(poor flavour)they are old. A lot of supermarket eggs come from storage.
Dark yokes(orange) are more than likely range fed chickens. Better flavor. Chickens need calcium to strength the shells, and grit, to help grind their food.
By the way, you don't need a rooster to get eggs, only to fertilize the hen if you plan to incubate the eggs.
Eggs white or brown, where would a good breakfast be without a egg.
