Just a forewarning:
If you take chickens (and a rooster) when you embark, don't nest them in a closed off area. What happens usually (in the open) is that the chickens lay the eggs, and your dwarfs will take them to a food stockpile. If the area is closed off, the eggs will be fertilized by a rooster, making more chickens. This cycle keeps going, faster and faster, and suddenly you find yourself with over 150 chickens, with 1 frame per second.
On the df forums they call it a chickensplosion.
