I love chickens! They're one of my favorite animals, and it one of the most common and widespread domestic animal.
Chickens are awesome! And they make really good pets.
I agree! .Studies have shown that the chicken has originated in the Indian subcontinent. 
I didn't know that. They are very common in North America now, but mostly for food.
That is true, now they are commonly used for meat and eggs.
I love eating eggs, especially when they are fresh from the chicken.
Egg as food
Some eggs are laid by female animals of many different species, including birds, reptiles, amphibians, mammals, and fish, and have been eaten by humans for thousands of years. Bird and reptile eggs consist of a protective eggshell, albumen (egg white), and vitellus (egg yolk), contained within various thin membranes. The most commonly consumed eggs are chicken eggs. Other poultry eggs including those of duck and quail also are eaten. Fish eggs are called roe and caviar.

Chicken
The chicken ("Gallus gallus domesticus") is a type of domesticated fowl, a subspecies of the red junglefowl ("Gallus gallus"). It is one of the most common and widespread domestic animals, with a total population of more than 19 billion as of 2011. There are more chickens in the world than any other bird or domesticated fowl. Humans keep chickens primarily as a source of food (consuming both their meat and eggs) and, less commonly, as pets.
