Look at the head Under normal circumstances, the size of earth eggs is relatively small, and the color of a single egg is relatively uniform, but the color of eggs laid by a chicken is not necessarily the same. If you see that all eggs are the same color and larger when you buy eggs in the market, then the probability of being foreign eggs is very high.

2

Hardness of eggshell. The calcium content of soil eggs is relatively high, and the eggshell of eggs is relatively hard. You can feel the hardness of eggshell by gently pinching with your hands, and choose eggs with relatively hard eggshells. Of course not, but from this point of view, some chickens raised with feed also lay hard eggs, which is related to feed, so we should choose them comprehensively.

three

Look at the egg white. The egg white of earth eggs is sticky, with a little yellow color, which looks crystal clear, while the nutrition of foreign eggs is not rich enough, the egg white is thin and the color is white.

four

Look at the yolk. Open the eggshell, you can see that the proportion of egg yolk is relatively large, and there are many egg yolks. Then you can gently pick up the yolk with a toothpick, but foreign eggs are hard to do.

five

Scrambled eggs. Break the egg, mix the yolk and egg white evenly, and then stir-fry. If the egg is found to be scattered, it means it is a foreign egg. If the eggs are connected together, it means it is a native egg.
