A fresh egg will sink in water, but a 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. Bown 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.
