I live in CA, the mountains. Today it was 80-90 and the baby chicks (now four weeks) hung out outside in a pen with a cover. Well, now they are back in the garage with the window open but the garage is hot. I'm not using a heat lamp as they don't need it. What night temps are high enough that I should just move the girls outside? Seems they'd be more comfortable outside than in the garage, but maybe not. I don't have a thermometer but I'd guess it's 85 in the garage right now.
