eggs

In the U.S. in 1998, hens produced 6,657,000,000 dozen eggs - that’s 6.657 billion dozen! After these eggs were laid, about two-thirds were sold in the shell and one third of them were broken - not by accident, but on purpose. Because after the eggs are broken out of their shells, they can be made into liquid, frozen, dried and specialty egg products.
The egg shell may have as many as 17,000 tiny pores over its surface. Through them, the egg can absorb flavors and odors. Storing them in their cartons helps keep them fresh!
Eggs age more in one day at room temperature than in one week in the refrigerator.
Occasionally, a hen will produce double-yolked eggs throughout her egg-laying career. It is rare, but not unusual, for a young hen to produce an egg with no yolk at all. It takes 24 to 26 hours for a hen to produce an egg; there is 30 minutes between each egg-producing cycle.
About 240 million laying hens produce about 5.5 billion dozen eggs per year in the United States.
Egg yolks are one of the few foods that naturally contain Vitamin D.
