FarmVille Nursery Barn finally gets a purpose: Raising baby animals

FarmVille Nursery Barn also underwent a few changes in the May 28 update -- basically, now it's a building that does more than contain your wobbly legged livestock.

Now those doe-eyed baby calves and foals can now grow up in to adult animals. Each time you harvest the Nursery Barn, you'll have a chance that one of your animals will grow into an adult. You'll also get a baby animal that you can share with your friends.
