So, I need to know if I can unplug the heat lamp in the brooder for my 2 1/2 week old chicks. They are way too hot and have been panting. I have been unplugging the lamp for 20 or so minutes a day because it gets so hot in my garage. Will it hurt to leave it off over night? I have one really tiny chick I'm mainly worried about getting too cold. Shes still the size of a four day old chicks. Please let me know ASAP
