If you use light bulbs or heat lamps, you should use more than one in case one burns out. The heat will give your chicks a better chance of surviving until you can replace the one that is burnt out. The 3rd part of the brooder box is the flooring or the bedding of the brooder box. You can use wood chips or peat moss, but you should avoid fine sawdust because it can clog the chicks crops which will kill them. You should also avoid cedar because it can affect the color of the chickens.
Some people use paper towels, but never use newspaper because it is too slick for the chicks.
In our brood box, we use mesh wire flooring. You have to be careful to make sure that the mesh of the wire is small enough that the chicks will not get their feet caught in it. The nice thing about wire mesh is that the chickens manure falls through making clean-up easier. If you use litter, you must clean up often. FEED- Chicks should be fed chick starter for the first 8 weeks.
