I can tell the difference because the yolks are so much richer. But to me it's not so much of tasting different as knowing what's in those shells. I know certain feed contains poison, well poison to us. Chickens that are grown out for KYC and all the other chickens eateries, are fed arsnic to speed growth. Don't know about the rest of you but I don't care for that one bit. So I feel better knowing what going in what I eat. Egg are just one the things I eat, so I feel better about it.
