I am frugal. I ultimately picked our chickens based on cost. It should come as no surprise that I didn't order a complete brooder kit. Not only do I want to avoid wasting money, but I think it is important and more sustainable to reuse what you already have. There are several plans on the internet and in the books I checked out of the library to build brooder boxes. We have some wood on hand and I could always hunt out heat treated pallets if I needed more, but even building something from the ground up seemed wasteful. All you really need is a draft free secure space, where you can regulate the temperature. I saw pictures of brooders made out of wading pools and fish tanks, but I didn't have anything like that on hand. I wandered my house a few times while trying to think of what I could use to make a brooder.
