Rock Chick - Goat, Sheep, Ram - all the same. Depends on which source you ask. :-)

We ate at Chinese buffets all weekend, I wore red, and my little Chinese sheep symbol, and we put up one of those neat paper dragons, and drank tea. I finally bought me one of those little celadon Chinese tea sets. It's way too cute.

There are lots of Internet resources for Chinese astrology, if you just search.
