I grew up on a farm with free range chickens (more like pets)....I found the yokes more rich and flavorful than the store bought. I don't know if there is any nutritional difference between free range and store bought but there is a taste difference!

Also on a side note,..not all brown eggs from the supermarket are free range/organic ...some types of hens lay different colored eggs. We had some chickens that layed white, others brown, and one that use to lay pale blue.
