What to do with eggs from a secret nest
If you do come across eggs in a secret nest and you’re not sure how long they have been there, you can do the float test.
Place the eggs in a bowl or bucket of water. If it sinks straight away it is fresh. If it stays on the bottom but one end raises up, it is not quite as fresh. If it stands on its end it is getting old and stale. If it floats, treat it gently and dispose of it as it’s a sign it’s full of gas and you don’t want that to explode anywhere near you.
Consider also the condition of an egg in a secret nest, even if it passes the float test. If it’s covered in dirt or manure, it’s best not to risk eating it. The shell of an egg is porous and will absorb bacteria through it, which could cause you problems.
If you still want to crack an egg open and you’re not confident about its age, crack it into a separate bowl just in case it’s hiding a nasty surprise.
If an egg rises or floats, discard it. Be careful as an exploding egg gets everywhere.
If an egg sinks to the bottom straight away and lies on its side, it’s fresh. If it sits on the bottom but one end is raised, it’s not quite as fresh, but still edible.
