Chicken

Chickens are a peaceful mob in the Minecraft: Pocket Edition. If killed, it drops Raw Chicken and 1-2 Feathers, which can be used to make arrows. Chickens are the mob with the least health. As for the 0.7.0 updates, they now drop eggs to make a cake or to be thrown to get the chance of a baby chicken hatching. If they are pushed off a cliff or into a hole they wil glide gracefully down slowly wilst waving their wings, taking no fall damage on the landing

Baby Variant
Introduced in version 0.6.0 the chicken has a baby version of it. When killed, it drops nothing.
