I just got done making mine (using "the chicken chick's" directions calling for a 40 watt incandescent bulb and 10" tin) but it is way too hot. It said it would be warm to the touch but mine is hot to the touch. I have plastic waterers which I'm sure it would melt, though I see plastic waterers in the pictures. Also I'm very concerned about fire w/ how hot it is. I need to use it in the morning as temps are going to be in the low 20's all day long for the next couple days. Any advice?
