FarmVille has been releasing larger items at a slow pace to avoid problems during releases. Well, add pig pens to that list, as they are being SLOWLY released to the players. If you recieve one, the first thing you will notice upon loading the game is a instant popup telling you they are here! The Pig Pen will show up in your giftbox or it can be purchased later on from the Market (If need be) for 5,000 coins. Remember, you must recieve the pop ups in order to start the building.
