Walmart here has egg whites, don't know about everywhere else.
Any grocery store should have them. At some stores though its actually cheaper to just buy eggs and seperate the yolks out.
Good grief, are your chickens special or something? lol
As for whites, I don't like the flavoring of the yellow color they add in, so I either sep. it myself, or buy the Real Whites kind that is 100% whites w/ no added coloring (I believe WalMart carries it).
No Special chickens or super eggs. The "free" healthcare cost has to be paid somewhere though, groceries are pricey. My neighborhood Walmart has the all natural egg whites by the way.
