I'll post a pick of this when the wife brings the camera back,, but what i am using for my first chicks is box that a truck tool box comes in. The box is two piece and slides together like a pill capsule. I cut the top out of it leaving the very end ot the outer piece in tact to keep the sides from spreading apart. I havent read the entire brooder sticky but I thought this is kind of unique because it can slide out and adjust the size from about 2ft by 4ft to as much as 2ft by 8ft giving me a little more room if i need it before I get my outside brooder built. I saw the box @ my local napa and the light bulb went off for me. I asked about the box and viola I had my temporary brooder. I'll post a pic as soon as i can
