Soon, your farm will be filled with little piglets, oinking and slopping around in your Pig Pen. Pig Breeding has arrived in FarmVille, and luckily half of the work has already been done for you. To start getting your Pigs hitched, you'll need a completed Pig Pen. If you've yet to build one, check out our guide right here. (Don't worry, we'll wait. You're good? Cool.) But to take a crash course in the basics of Pig Breeding, join us behind the break.
