If the shell of a duck egg is white, it is still rough to the touch, or it feels thin, mostly because the duck laying the egg is not strong enough, and such duck eggs are not easy to store. In addition, you can also pick up the duck eggs and shake them. If the quality is good, you can feel the eggs tremble slightly inside.

2. Listen to the sound: the duck eggs commonly known as "iron sound" in the industry have no pores, and the skin is particularly smooth. When you flick your finger or knock two duck eggs lightly, it will make a slight and sharp sound. This kind of eggs is very small, so it's okay to eat. If you make preserved eggs or salted eggs, it's not possible. The reason is that duck eggs without pores are still fresh eggs after being salted for a month.
