You remember buying a crate of eggs, and when you got home and cracked them, some were fresh, some were getting old and some were really bad.
Then, you really need to test the eggs before even buying them.

Below is how to check it:

Check the expiring date

Usually, eggs don’t stay more than 30 days in a store. It’s not like the eggs go bad after the date, but it will help guide you on not buying old eggs.
So, if you’re buying your eggs from the stores, always check for the expiring date.

Smell and Colour

If you don’t buy from stores, your nose and eyes will do the work here. Once the eggs start to have a bad smell then you know that it is bad.
The colour of shell are very vibrant. Once the colour starts to look different or starts looking dull, then it is bad.

Water test

When you have already bought the eggs, you can conduct a water test. In the picture below, if the egg is at the bottom, then it is fresh, if it floats a little then it is getting old, once it gets to the top then it is bad.
