Why would you want to shake an egg particularly if it is incubating - the reply is a definite no I wouldn't shake an incubating egg
To determine if an egg is fresh, shake it gently next to your ear. If you hear a sloshing sound, the egg is likely not fresh. If you don't hear anything, the egg is fresh.
You can shake an egg to determine if it is raw or hard-boiled by gently shaking it near your ear. If the egg makes a sloshing sound, it is raw. If it does not make a sound, it is hard-boiled.
