Thanks, they're getting so smelly I've been trying to hold off bringing them out there with the lamp. But I think it's time as long as they'll be alright. There's no drafts at all either in there.
I have 12 chicks almost 4 weeks old, I'm wondering when I can put them in the barn with the heat lamp on of course still. I know some start in garages/barns etc. It's about 35-40 degrees F outside lately. Some warmer days around 50. Would they be ok in their brooder in the barn with the heat...
