Fresh egg sinks in water, stale one won't.

Can't remember if an egg is fresh or hard boiled? Just spin the egg. If it wobbles, it's raw. If it spins easily, it's hard boiled. A fresh egg will sink in water, a stale one will float.

Eggs contain all the essential protein, minerals and vitamins, except Vitamin C. But egg yolks are one of few foods that naturally contain Vitamin D.

The colour of the egg shell is not related to quality, nutrients, flavour, or cooking characteristics. White shelled eggs are produced by hens with white feathers and white ear lobes. Brown shelled eggs are produced by hens with red feathers and red ear lobes. Brown egg layers usually are slightly larger and require more food, thus brown eggs usually cost more than white eggs.

China produces most eggs, at about 160 billion per year. In the US, about 260 million hens produce more than 65 billion eggs per year. A hen can lay about 250 eggs per year.

An egg shell has as many as 17,000 pores over its surface.

There are 150 species of chicken.

Chicken are descendants of the red jungle fowl (gallus gallus spadiceus) that lives in Asia.

The chicken is one of the first domestic animals, appearing in China around 1400 BC.....

Animals

Is a world population of 6 billion too many? Compare that with animals. There are more than a million animal species. There are 6,000 species of reptiles, 73,000 kinds of spiders, and 3,000 types of lice. For each person there is about 200 million insects. The 4,600 kinds of mammals represent a mere 0,3% of animals and the 9000 kinds of birds only 0,7%. The most numerous bird specie is the red-billed quelea of southern Africa. There are an estimated 100 trillion of them.

Mammals are the only animals with flaps around the ears.

African elephants only have four teeth to chew their food with.

There are about one billion cattle in the world of which 200 million are in India.

And last. A house fly lives only 14 days.
