So I started a pretty grandiose brooder this evening. I have a finished 8'x4' 34" tall framed brooder. Don't ask me what exactly I plan on putting in there, but it's framed now. My question is for a brooder I'd like to be able to "plug it in" to a nearby outlet and have a switch inside that I can flick on. I'm planning on being able to split it in half with a divider if I have a brood and a broody at the same time, so I'd have two lights inside it theoretically. Should I run 12gauge wire between the studs and then cover them up inside and out like a "finished" frame would be? I'm in Arizona, so I don't really get cold, but I am concerned about it getting hot, and thinking of having another switch for a fan to turn on... cripes! Any idears?
