The subject of this section was part of FarmVille's 1st Birthday, an event that lasted from June 17, 2010 to July 1, 2010. Since the event has run its course, this may no longer be available. For the birthday sheep released during the Second Birthday Event, see Birthday Ewe. The Birthday Sheep is an animal available in FarmVille. They were released as a reward for mastering the limited edition job FarmVille's birthday in co-op farming. A Birthday Sheep takes 3 days to grow and produces wool, which can be sold for 28 coins. To complete the co-op, farmers must grow and harvest cupcakes.
