Question everybody--what do you find best to use as brooders that's a low risk of catching fire? I use to use metal tubs (which I'm not a huge fan of) and rubbermaid tubs back in the day. I haven't had chicks in years though. After surviving an arson last year, I'm very hyperaware of anything that "could" catch on fire. How flammable are the rubbermaid tubs? Has anyone had one catch on fire? I just want to minimize the risks as much as possible!
