In a group of chicken eggs,how do you know which are fresh and which are old

To determine whether a chicken egg is fresh or old, you can perform the "float test." Here's how you can do it:

1. Fill a bowl with enough water to completely submerge an egg.

2. Gently place one egg at a time into the bowl of water.

3. Observe the egg's behavior:
- If the egg sinks to the bottom and lays flat on its side, it is fresh.
- If the egg stands upright on one end, but still touches the bottom, it is less fresh but still safe to eat.
- If the egg floats to the surface or stands upright on one end, with the widest part of the egg at the surface, it is old and should not be consumed.

Floating occurs because, over time, air accumulates inside the egg, causing it to become less dense and float. This is a sign that the egg is losing freshness.
