How to tell If the eggs are fresh or not?

Float test

Carefully submerge an egg in a bowl filled with water. If the egg jumps to the surface and starts to float, it is old. If the egg settles down at the bottom, it is fresh.

After an egg is laid, its temperature drops during which an air cell forms inside of it at the larger end. This space grows larger due to continuous evaporation. Therefore an older egg with a larger air cell floats over water.

Egg candling

Egg candling is performed using a candling lamp to check the stage of chick development inside a fertilized egg. It can also be used to check the freshness of an egg.

A bright light source is used to see through an egg from its broader side. If it looks empty or you feel the egg contents moving inside because of larger air space, the egg is old.
