FarmVille Fan Calf!
If you are a fan of the FarmVille Cow's Facebook fan page, you may purchase the Fan Cow in the FarmVille Market for 12 FV$. Also, you may receive a Fan Cow for free if you adopt one from one of your kind FarmVille neighbor's Facebook newsfeed. Note, with the purchase of every Fan Cow, you may share one with a FV neighbor.
The Fan Cow can be placed into Dairy Farms for the chance of yielding a Fan Calf. If you produce a Fan Calf you will have the ability to share it via Facebook newsfeed and give your FarmVille neighbors the opportunity to adopt! The only way to receive a Fan Calf is by adoption.
