| Rotation Methodology | Description | Function |
|—|—|—|
| Full rotation | Rotate the egg 360 levels | Offers a whole view of the egg’s contents |
| Half rotation | Rotate the egg 180 levels | Permits for targeted examination of particular areas |
| Tilting and tilting | Slowly tilt the egg backwards and forwards | Helps decide the scale and placement of the air cell |
| Mild shaking | Gently shake the egg side-to-side | Checks for unfastened or floating membranes contained in the egg |
Observing the Egg’s Inside
After you have sufficiently darkened the room and held the egg as much as the sunshine supply, you may start to candle the egg. Observe the next key options of the egg’s inside:

- Eggshell: The shell needs to be clean and intact, with none cracks or dents.
- Embryo (Fertilized Eggs Solely): If the egg is fertilized, you may even see a small, darkish spot on the yolk. That is the embryo.
| Remark | Interpretation |
|---|---|

3. Older Egg
The yolk will probably be noticeably off-center, and the air cell will probably be bigger. The albumen will probably be barely cloudy.
4. Stale Egg
The yolk will probably be very off-center, and the air cell will probably be very massive. The albumen will probably be cloudy and watery.
5. Cracked or Leaking Egg
The egg may have a visual crack or leak. The contents of the egg could also be leaking out.

If the massive finish of the egg has an air cell of 6mm or much less, which implies that the egg is recent. If the air cell is bigger than 6mm, which implies the egg is stale.
Flashlight Take a look at
Shine a flashlight by way of the egg in a darkish room. Recent eggs will seem practically opaque, whereas stale eggs will enable extra gentle to move by way of.
Troubleshooting Candle Outcomes
Interpretation of Outcomes
Clear egg: Signifies a recent egg with a agency yolk and agency white.
Small air cell: Lower than 1/8 inch (3 mm) excessive, signifies a really recent egg.
Medium air cell: Between 1/8 and 1/4 inch (3-6 mm) excessive, signifies an egg that’s nonetheless recent and of fine high quality.
Massive air cell: Over 1/4 inch (6 mm) excessive, signifies an older egg however nonetheless suitable for eating.
Troubleshooting Ideas
Yolk touching the shell: Signifies a weak or damaged eggshell. Discard the egg.
