An egg is a round or oval body laid by the female of many animals, consisting of an ovum surrounded by layers of membranes and an outer casing, which acts to nourish and protect a developing embryo and its nutrient reserves. Most edible eggs, including bird eggs and turtle eggs, consist of a protective, oval eggshell, the albumen (egg white), the vitellus (egg yolk), and various thin membranes. Every part is edible, although the eggshell is generally discarded. Nutritionally, eggs are considered a good source of protein and choline.Roe and caviar are edible eggs produced by fish.

Apparently many residents keep them for the fresh eggs. One would think the Chicago pols would not want to see chickens leave where so many vote for daley & company.

People who want fresh eggs should be able to keep their own hens around the house or yard...

Chickens are no clucking matter to one city council member in this college town. Stephen Kunselman says people who want fresh eggs should be able to keep their own hens around the house, or yard. The Democratic lawmaker brought up the proposal at a weekend council retreat.

"It's only their fault for letting foxes get into the henhouse and then wondering why there's no eggs or chickens. Every little college kid, every freshly-scrubbed little kid's face should have been sued off the face of the earth. They should have taken their houses and cars and nipped it right there in the beginning."-Gene Simmons

igloos, for chickens. There's also a 30-day money back guarantee on the chickens. haha
