Today marks a special day for animal lovers in FrontierVille, who may be questioning selling off some of their adult animals simply because they take up so much room. Now, a Livestock Pen is available to build on your Homestead, that will allow you to store adult Sheep, Goats and Pigs inside. Of course, you won't simply receive a completed Livestock Pen - you'll have to build one from scratch.
The frame of the Livestock Pen is available for free, and you'll receive it once this update rolls around to your game. You'll need to whack the frame (each whack costs 15 Wood), and you'll then need to collect six all new ingredients to finish the building off.
