- The most yolks found in one chicken egg was 9! Imagine incubating that!

- Eggs are about 105*F when laid and as they cool down the liquid inside contracts, forming an air cell at the large end of the egg.
- An egg is laid large end first and gets coated in a liquid called a "bloom".
- You can rub off the egg shell colour if you can get to the egg just as it's been laid, before it dries off. Once it's dry though, no amount of rubbing will have any effect on the colour.
