I agree. I have my own chickens and sometimes for whatever reason don't have enough eggs so buy store bought and I can tell zero difference.

Now, I CAN tell a difference between the eggs of different types of fowl. For example.... I don't care for duck eggs other than for baking... I like my eggs over easy or soft scrambled and do not like the texture of the whites of duck eggs. On the other hand, I find quail eggs much superior in taste to chicken eggs.

But store bought vs. homegrown chicken eggs? Naw.... no difference other than in color.

While we are on the subject. We usually have a few extra when the girls get rolling in the summer. When we get to far behind I put them in bags and hang on neighbors mail boxes in the am. going to work. A couple years ago one of the recipients called me. Really liked the eggs but, going forward if I left some she didn't want any with brown shells as she didn't eat brown eggs. G.

The whites are about the same but the yokes have much more flavor.

^^^^^^^
This, free run eggs yokes taste stronger, more flavorful .
I laugh at people that think brown eggs are better than white or any other color eggs.
But if the farmer can get more per dozen for brown eggs, good for them.

Yes duck, goose, eggs are a lot stronger tasting than chicken eggs , never tried quail so don't have a clue.
I like my farm free range eggs, if for nothing more than the color of the yoke. Support local farmers also.
