Free range chickens produce stronger tasting eggs with more color in the yolk. Also the eggs produced vary significantly with what plants are growing in the area and what is in the soil. Some like the strong flavor. Some don't.
Floor based chickens vs caged eggs differences are less prominent but can taste different.
The most consistency in taste is cage system produced. Even those eggs can vary in taste from one farm to another depending on feed ingredients, particularly if fish meal is used as a protein & calcium source.
