Interesting Egg Facts
- The average hen lays 250-300 eggs a year
- As a hen gets older, she lays larger eggs
- A mother hen turns her egg about 50 times a day
- When an egg is laid, it comes out large end first
- An egg shell contains holes to let CO2 out and let air in
- Eggs are laid between 7:00 am and 11:00 am
- Egg shells can be white, brown, green, or pink - the shell color is determined by the breed of chicken and has no bearing on the nutritional value of the egg
- When eggs are laid they are about 105 degrees farenheit - as it cools, the membrane pulls away from the shell creating an air cell. The larger the air bubble at the end of the egg shell, the older the egg. If the egg floats in water, the egg is old.
- The chalaza (white stringy part that clings to the yolk) is what delivers oxygen to the chick (if the egg is fertilized).
- Cloudy egg whites indicate a very fresh egg; clear egg whites indicate an aging egg; pink egg whites indicate the egg is spoiled - do not eat it
- The 'grade' of an egg is based on the air cell within the egg (grade A = 3/16" deep air cell)
- It takes a hen 24-26 hours to form an egg and starts generating the next egg 30 minutes after laying the last one
- The egg white (albumen) contains 57% of an egg's protein.
