Well I was looking in my barn and I realized I could build a good size brooder just from stuff laying around in the barn. so here we go, I took an old set of saw horses for the base, added a couple of 2x6 on the flat to hold the base. I had a old sheet of concrete board from my fireplace install. I used that as the base. When I built my fireplace I used cultured stone and it came in these heavy duty boxes with 2x2 in the corners of the boxes for support. I ripped all those out and used them to build the brooder walls. I then cut up one box and stapled them to the sides of the brooder. The only thing I have to buy for the brooder is a light, feeder, water dish, and some wire mesh for the top. Not too bad.
