The appearance may be different: the fact is that the color of eggshell depends on the variety of hen, and has nothing to do with the nutritional composition of the egg. In addition, the color of egg yolk is influenced by chicken feed. Adding colored substances such as carotene, vitamin B2 and lutein to the feed will affect the color of egg yolk. It is not scientific to judge the nutrition of eggs by color.

Breeding methods are also different: because of the different feeding methods, the fat content of soil eggs is slightly higher, but the unsaturated fatty acids and phospholipids with health care function are slightly higher. The feed eaten by ordinary chickens is scientifically matched and dietary fiber is added, and the cholesterol and fat content are slightly lower.

Nutrition really doesn't make much difference: the difference in protein is less than 2%, and the calories of earth eggs may be slightly higher.

As for the taste, many people say that the real earth eggs taste better than ordinary eggs because of their long production cycle, low water content and high fat content, but I didn't eat them.
