In a few years I want to be able to get some chickens. I love the idea of using some kind of existing structure to make a chicken coop from. It would be neat if it could look fun and and still be functional.

A friend of mine built a coop all with wood and metal sheeting and other stuff he found at the dump. With a little paint, it looks almost artistic.

Does anyone have any fun ideas for things you could use as a basis for a coop?
