Whole eggs offer almost every essential vitamin and mineral needed by humans (with the exception of vitamin C).

You can tell cooked eggs from raw eggs by spinning them. Raw eggs wobble whilst cooked eggs spin easily.

The size of an egg is measured by its weight rather than its size. That is why you will sometimes get different sized eggs in a carton.

Brown eggs come from brown hens and white eggs come from white hens. The colour is no indication of quality.

Eggs are graded by rolling them over a high-intensity light which makes the egg transparent so the grader can check the inside of the egg for quality. Historically candling was done by holding the egg up in front of a lit candle. This is how this part of the grading process got its name.

It takes a hen 24 to 26 hours to produce an egg.

Eggs have everything inside them that a baby bird needs to grow to the point of being hatched.

The eggshell may have as many as 17,000 tiny pores over its surface through which air can get in and out of the egg for the growing baby bird.

These same pores mean that the eggs are also able to absorb the odours of any strong smelling things that are stored nearby such as onion or strong cheese.

Do not wash or wipe eggs. Egg shells are covered with a natural coating called "bloom" which seals the pores to help prevent bacteria from getting inside the egg and reduces moisture loss.

Egg size is usually dependent on the age of the hen - older hens lay larger eggs.

The thickness of an eggshell is also dependent on the hen's age. The older hens lay larger eggs but still only have the same amount of coating to make the shell so therefore the shells are thinner.

Egg yolks are anchored to the white by tiny strands of egg white called chalazae (pronounced ka-LAY-zee). These keep the yolk centered in the thick white.

Egg yolks are one of the few foods that naturally contain Vitamin D.

Double-yolkers are created when a hen releases two yolks at the same time. This is quite common in young hens whose cycles may not be perfectly synchronised yet. Older hens will sometimes produce a double-yolker in an extra large egg. Sometimes a young hen can produce an egg with no yolk at all!

Eggs are nutritious for many pets as well as humans and are often an important part of prepared pet food formulas. If you find a cracked egg in your carton - give it to your pet as a tasty treat (no more than 1-2 raw eggs per week).

Eggs Benefit diseases such as: Adrenal exhaustion, Anemia, Blood clots, Brain and nervous system disorders (like Dementia, MS, Parkinson's, and ALS), Breast cancer, Cardiovascular disease, Digestive disorders, Gallbladder trouble, Macular degeneration, Memory challenges, Osteoporosis, Poor hair/coat, and Skin disorders.

Eggs should always be stored in the refrigerator. They lose their quality very quickly at room temperature. Eggs age more in one day at room temperature than in one week in the refrigerator.

Eggs should also be stored in the carton that they are bought in to help prevent absorbtion of other odorous foods.
