I am thrilled!!!! Finally ordered chicks.....so.... I was thinking that the spare 150 gallon water tank (rubbermaid black) might work well for a brooder but am not sure if it is the best size. It will fit into the house and I can make a cover for it that hinges and hang the heat lamp easily and adjust height. I have a month to get ready in... Will this work and is it big enough for 30+ chicks?
