I brought in an old round metal wash tub to use as a brooder. My daughters are afraid that the metal will get hot and bake the six chicks that we are getting tomorrow. Should I leave just the hardware cloth on top for a cover so they get enough ventilation? Or should it be covered with something more substantial (just leaving part of it open to the hardware cloth). I know I need to get a thermometer so I can check the temperature. How far away should the lamp be initially? I saw (in the brooder photos section) lots of folks just leaving the lamp sitting on the hardware cloth. Should I put anything under the paper towels? and How long before I switch out paper towels for pine wood shavings? Should I have wood shavings under the paper towels in the first place? What is the best thing to use to combat odors? Thank you very much.
