There is no nutritional difference between white or brown eggs per se.

However, free-range eggs .. no matter what colour is the shell .. are definitely more nutritious for the very reasons Junebug stated These foods that the chicken eats will increase the omega-3 fatty acid content of the egg yolk. Most battery chickens are fed grains and soy, which are high in omega-6 fats. Some chickens are given flax seed in the grain mix, which improves the fat in the yolk somewhat, but still not as good as free-run chickens that are allowed to eat scratchings.
