It's what I've always used here, and it works very well. Right now I'm using a rubbermaid tank, but the metal tanks work equally well.
Mine is in the garage, on styofoam insulating boards, and has maybe 3" of shavings as bedding, which I add too as needed.
The heat lamp is suspended over one end, and a hardware cloth top is over the whole thing.
Initially I have styrofoam boards over the cool end of the tank, to help keep the temp better for the chicks. It needs to be about 95F right under the heat lamp, and maybe 65F to 70F at the other end.
Then I watch their behavior! The top insulation gradually is eliminated in a few days, and the heat lamp is raised, and the bulb wattage lowered, as time passes. The birds move to their coop section by 2.5 weeks of age, with their heat source.
