Our heat bulb is blown or something like that. It won't work. Anyway, will the chicks be ok for tonight? It is supposed to get down to 66 and it is very humid. And it's supposed to rain, so I don't know if that will cool it off more then the forecast says. The brooder is outside in a large shed with a large open doorway. There are 15 chicks and they are about a month old. It is a big brooder. Anybody?
