Look at the appearance is not very uniform
If it is a real egg, there will always be some defects, because some chickens are not in good condition, the appearance of the egg is not very beautiful, there may be some coarse pores, the grain may also have some disorder, if you buy, both the pores and the grain is very uniform and very beautiful and very clean, then we have to think about it! Is not a fake egg. Real hens can't lay perfect eggs.
Smell the flavor to see if a little fishy
Because it is a kind of eggs, so the real eggs themselves are some fishy, if close to smell will smell that how can not hide the taste, if the smell of a little fishy did not, then we have to consider it is not a fake. But if you haven't gotten close enough to smell a very strong flavor, this kind of egg can't be bought, which means it's already bad.
Shake to listen to the sound
The structure of the egg itself is still relatively stable, so it is not a problem to shake it a little, if you can hear a very crisp echo, it means that this is a real egg, and if the sound is very muffled, then it may be a fake egg. Even if a fake egg looks like a fake egg, it can't simulate the natural crisp sound of a real egg. But don't buy them if they make a very loud, watery sound when shaken, which means they've been sitting around for too long and are very unfresh.
Look at the exterior to see if it is smooth and shiny
If the hen is in good health, then it may produce some smooth eggs, but it is not completely smooth, there will always be some abrasions, and if the hen is sick, the eggs will be very rough, so if you see that the surface of the eggs that you buy is very beautiful and smooth, then that means that you may have bought a fake egg.
