I'm not the person you are replying to, but I have empirically not tasted the difference. The only difference between store bought eggs and farm fresh ones is that the yolk is vividly yellow on the ones from the farm. I am willing to bet that the people who taste a difference are imagining it because of the superior aesthetics, and that they wouldn't taste anything different in a double blind taste test. Which is fine, nothing wrong with the placebo effect. But I don't think there's any substance to the claim that the eggs actually taste better.
