Egg what is inside

Easter came early for a chicken-raising family this year. Instead of a chocolate candy inside an egg, they got a Russian nesting doll-style surprise.

YouTube user SNO Multimedia posted a fascinating video over the weekend showing a giant mutant chicken egg. The lumpy-looking creation dwarfs a normal egg. When cracked open, the egg reveals a yolk and another fully formed egg inside. That smaller egg also contains a regular yolk and white. Though the egg-inside-of-an-egg phenomenon is rare, it does happen. The air cell grows larger as an egg ages.

The yolk contains less water and more protein than the white, some fat, and most of the vitamins and minerals of the egg. These include iron, vitamin A, vitamin D, phosphorus, calcium, thiamine, and riboflavin. The yolk is also a source of lecithin, an effective emulsifier. Yolk color ranges from just a hint of yellow to a magnificent deep orange, according to the feed and breed of the hen.

These membranes protect the contents of the egg from bacteria and prevent moisture from leaving the egg too quickly..

As cooling takes place, the contents of the egg contract more than does the shell of the egg. This creates a vacuum and air is drawn through the pores of the egg. As a result, an air cell forms at the large end of the egg. While the embryo is growing, the shell membranes surround and contain the white or albumen of the egg.

The albumen provides the liquid medium in which the embryo develops, and it also contains a large amount of the protein necessary for proper development.
