FarmVille and Zynga are SLOWLY rolling out a new feature that will allow players to store Animals and Trees! This is a great new feature that will let you keep all your goodies and store them if need be. You can see on these screen shots from my farm that I was able to store my new Irish Moiled Cow and also see it in storage. They are stored under the correct tabs in storage and is easy to find.

Questions: Do you have this new feature yet? Will this help free up room on your Farm?
