I needed more room for my chicks, but with less space, so I found this storage container on sale at WAL for $15. and it has wheel you can put on or stack them. I had Hubby buy these light bulb holder thingies and screw them into the back of each drawer after drilling a small hole for the cord. Each drawer has it's own plug so it can come out and be cleaned easily. I can wheel it around the room and it takes up less space. It only needs a 25 watt bulb in each drawer, less if I could find one and I can open and shut the drawers for more ventilation. It has gaps around sides and back to let air flow around. It was simple and affordable.
