From everything I've read here (and in my own experience), the best layers are brown egg layers. So why is it that the cheap commercial eggs are white? What kinds of birds are they using?
Lots of misleading an inaccurate info on this thread.
Commercial eggs are are white, because most of US consumer is used to white eggs, Part of NE being the exemption, in New England brown eggs are still preferred.
Color of egg shells is tided to genetics and breed not to what the birds are fed.
Commercial white egg layers are selected Leghorn strains, not some mysterious hybrids.
There is an "scientific" opinion that taste and color of the yolk of egg has nothing to do with egg shell, but depends solely on the feed.
This is highly controversial, and I have evidence to the contrary.
Friend of mine has 5 acres of pasture, part of it is cypress wetland. She's got white egg layers (california whites, Spitzhaubens) and brown egg layers mostly Orps and cuckou Marans.
Marans and orps yolks are more orange than white eggs, all birds are fed same food and forage the same pasture.
So genetics do affect yolk color and perhaps the taste, but taste can be subjective, color difference is obvious.
