I was pretty sure that I wasn't going to be able to do peeps this year, what with all I've got going on through the end of July -- but then the thought hit me: I can raise them in August! Anyone here do this often? I know spring is the usual time. Anyone manage to do it without supplemental heat, at least during the daytime? Anyone have a creative way to do it with supplemental heat -- but without electricity? I was thinking of using hot water jugs and doing away with the lamp altogether, since I will have to raise them outside this year as I've lost access to a garage that I don't have to ask permission to trash with chick dust. Two years in a row I've done lamps without being at all scientific (what's a thermometer again?), so I'm pretty well convinced that some temperature variation won't hurt, within reason.
