Egg Production and Distribution

Birds and eggs have existed since before Man and the first recorded history of domesticated wild fowl were found in East Indian history as early as 3200 BC. Records show domesticated hens throughout history but it has been believed that Columbus, on his second trip to the Americas in 1493, brought with him the ancestors of the chickens we see today. There are close to 200 breeds and varieties of chickens worldwide, but the most common laying hen is the Single Comb White Leghorn.

How Eggs are Classed and Graded

The grading of eggs is done with a series of tests where the eggs are examined for various qualities such as size and weight. There are three grades of eggs, which are Grade A, Grade B, and Grade C, in Canada. The grades in the US differ slightly by name only, as Grade A, Grade AA and Grade B. Grade A eggs are sold to consumers but the other Grades are for commercial uses.
