Inside for the first few weeks(longer if I hatch when the weather is cold) I use the large plastic totes with a light. I just line the bottom first with newspaper and cover that with paper shop cloth towels. I quit using shavings. They were too messy and the chicks don't really need it. With the newspaper under the shop towels,clean up is quite easy. When they go outside,I keep them in a brooder someone gave me,but a wooden box with a wire top and a light for cold times will do nicely. If the weather is mild and they are fully feathered,they go into a cage which used to be a rabit hutch.
