• A hen requires 24 to 26 hours to produce an egg.
  • Eggs age more in one day at room temperature than in one week in the refrigerator.
  • Hens with white feathers and ear lobes produce white shelled eggs. Hens with red feathers and red ear lobes produce brown shelled eggs.
  • To tell if an egg is raw or hard-cooked, spin it! If the egg spins easily, it is hard-cooked but if it wobbles, it is raw.
  • If an egg is accidentally dropped on the floor, sprinkle it heavily with salt for easy clean up.
  • Egg yolks are one of the few foods that naturally contain Vitamin D.
  • A pullet is a ‘young’ hen (like a heifer is a ‘young’ cow)
  • The egg shell accounts for about 9 to l2% of its total weight.
  • The shell is largely composed of calcium carbonate (about 94%) with small amounts of magnesium carbonate, calcium phosphate and other organic matter including protein. Shell strength is greatly influenced by the minerals and vitamins in the hen's diet, particularly calcium, phosphorus, manganese and Vitamin D. If the diet is deficient in calcium, for instance, the hen will produce a thin or soft-shelled egg or possibly an egg with no shell at all.
  • Shell thickness is also related to egg size, which, in turn, is related to the hen's age. As the hen ages, egg size increases. The same amount of shell material which covers a smaller egg must be ‘stretched’ to cover a larger one, hence the shell is thinner.
  • Eggs can be an important source of complete protein for vegetarians. One egg = 1 ounce of lean meat, fish or poultry.
