Male eggs are not laid by roosters, but refer to the testicles of roosters, which belong to the reproductive organs of roosters. When the rooster is slaughtered, you can see this organ. The male egg is only the size of peanuts to quail eggs, and it is a pink oval. The mother egg is the egg we eat in our daily life. The mother egg generally has a powdery white or yellowish brown shell with egg white and yolk inside.

In daily life, we should pay close attention to these points when buying eggs. Generally speaking, fresh eggs have rough surfaces and bright and clean colors. If they are stale eggs, their shells are dirty and even have some oil stains.

You can also listen to it when you buy eggs. You can judge the quality of an egg by shaking it next to your ear. When a good egg shakes, the sound is real, and it sticks to the shell or is a broken egg, and there is a crackling sound when it shakes.

If you have a flashlight or lamp at hand, you can take a photo of the egg, put the egg in a cylindrical light, aim at the sunlight or light, and shake the egg at this time. If the yolk of the egg has a shaking feeling, it is a stale egg. If the egg does not have a shaking feeling, it is relatively fresh.
