My dad just bought an old tractor. It was cheap. Reaaaal cheap. Probably because the engine was in pieces in a crate. Which brings me to my question. Can I pressure wash this thing out (with detergent of course) and convert it into a brooder? I plan on having six birds. The crate is 34" x 30.5". How much room would six birds need for their last week in a brooder before they move to the big chicken house?
