My nephew checked on his baby chicks the other night in their pole barn before going to bed. Somehow, the heating lamp got bumped and fell into their box, igniting the bedding, and then catching fire to the nearby bag of bedding shavings, wood, tools, machinery, and feed. The entire barn was engulfed and burned to the ground. They were able to rescue the truck and some of the shop tools, but that's it. Fortunately most of the contents and the barn were insured. The chicks didn't survive, and my nephew is understandably very shaken up. Moral; Use a metal, non-flammable container for growing chicks, especially indoors. An old stock tank or galvanized tub is great if you can get one. Cardboard and crates are cheap but flammable. Put a wire mesh cover on the container. Secure the heat unit to the cover to keep the heat unit from dropping down into the container and bedding. Clip lamps with heat bulbs are notorious for giving way and falling into bedding.... it's happened to me several times and we're pretty sure that's what happened to my nephew. When chicks are little, lower the heat unit with a wire solidly twisted to the fixture and then to the cover. Just a few precautions can save a lot of heartache and expense!
