A Barn with No Purpose

Our beautiful old barn is about 90% empty. I have yet to figure out a good use for it. Inside the all-wood structure are some "stalls" which would indicate to me that they were originally used to house some sort of animals... but what? I'm using a small corner of this barn for my chickens, but they rarely go in because it's so dark. 

I may use one of these stalls as a brooding area when I get my chick order in.

The kids like playing up in the amazing loft.

So.... any suggestions?
