If the egg is flat on bottom and not rounded off it good to eat?

It's not a good idea to eat an egg that's flat on the bottom and not rounded off. Here's why:

* Possible Cracks: A flat bottom often indicates a crack in the shell that might not be immediately visible. This crack could allow bacteria to enter the egg, making it unsafe to eat.

* Loss of Freshness: A flat bottom can mean the egg is old and has lost its internal pressure, which is a sign of freshness. Old eggs might have an unpleasant taste or texture.

Always look for eggs with a rounded shape and no visible cracks.

If you're unsure about an egg's freshness, it's best to err on the side of caution and throw it away.
