As you level up, you'll eventually get several storage buildings, such as barns and stables. Barns can hold other items, such as decorations, that you want to save for later. For example, if you played over Christmas and got the Christmas decor, you can stash it in your barn and bring it out once Christmas rolls around again.
Stables, chicken coops, and the like have a more functional purpose. These buildings allow you to "store" a series of animals. Then, clicking just the building allows you to harvest everything from all the animals: tons of cash from a single click! Vehicles are the same way, such as tractors, allowing you to harvest multiple fields with a single click.
Many of these objects need to be built up with a myriad of items, such as needing nails and boards for your barn. These objects are mainly gifted to you from neighbors, again proving that the primary rule of Facebook games should be your top priority. The more neighbors you have, the faster you can build click-saving buildings, and the less time it takes to get all your cash and experience.
Livestock and fruit are godsends for the casual player. .
Crops wither and die if not harvested quickly enough. However, livestock (which first unlocks at level 6) and fruit trees will remain ready to harvest indefinitely. If you don't think you'll play that often, or if you're going on vacation or something where you won't have access to a computer, load up on those so you'll have something to harvest once you get back on Facebook.
