- Dairy Farms were discontinued from the market, and new Dairy Farms cannot be purchased. However, existing Dairy Farms have not been removed from players farms.
Up to 5 (five) Dairy Farms could be purchased and placed on each farm. Each fully upgraded Dairy Farm could hold up to 40 (forty) cows or bulls of any type, including the Jersey Cow. Originally, only 1 (one) bull could be placed inside each Dairy Farm.
A Dairy Farm can be harvested every 1 day. When harvesting a Dairy Farm containing at least one Jersey Cow and any bull, players have a chance to find one Jersey Calf. When this Jersey Calf is shared to the player's wall, it may be adopted by the player's friends.
