What do eggs look like?

Eggs come in a variety of shapes, sizes, and colors, depending on the bird that laid them. Here's a general description:

Shape and Size:

* Oval: Most eggs are oval-shaped, with one end slightly wider than the other.

* Size: Eggs vary greatly in size, from the tiny eggs of hummingbirds to the large eggs of ostriches.

* Surface: Eggs can have smooth, rough, or bumpy surfaces.

Color:

* White: Many common chicken eggs are white.

* Brown: Also common, brown eggs are due to a pigment called porphyrin in the shell.

* Blue, green, or speckled: Some breeds of chickens lay blue, green, or speckled eggs.

* Other colors: Ducks, geese, and other birds lay eggs in various shades of blue, green, brown, and even pink.

Inside:

* Yolk: The yolk is the round, yellow part of the egg. It contains fat, protein, and vitamins.

* White: The white, or albumen, surrounds the yolk and is made mostly of water and protein.

* Shell: The hard, outer shell protects the egg.

Here's a fun fact: The color of the eggshell doesn't indicate the nutritional value of the egg.
