There is a belief that brown eggs are better than the white ones. And one of the reason is their price difference as brown eggs are more expensive. According to an article from Huffington Post, though, brown eggs are no better than white ones. There is no difference in their nutritional value, their shell strength or their yolk color. Brown egg shells are not harder than white ones: the hardness of the shells depend on the age of the laying chicken, not on the color as younger chickens lay eggs with softer eggshell. Also the yolk color only depends on the diet of the chickens. The reason in price difference is just because brown eggs are laid by chickens that are larger than those that lay white eggs and thus their feed costs more.  Also, white-feathered chickens with white ear lobes lay white eggs and red-feathered ones with red ear lobes lay brown eggs.

Do we need to find one that talks overall about why its good to reduce water use to include in our overall rationale of the irrigation section of the policy? Or can we assume it is it general knowledge that its economically and ecologically better to use less water…
