I buy the brown eggs at costco - cage free means they might have a 1x1 areas. Pasture raised is best - yolks are rich orange and hens eat natural omnivore diet.
I haven't seen pasture raised eggs at the Costco where I shop. Their brown eggs are cage free just like their white eggs, but they are "certified organic feed", unlike their white eggs.
They do have blue, free range eggs. I like them, but they're too expensive and they don't always have them.
