So I am keeping my brooder and chicks in my mudroom at the back door. My house is 82 during the day right now and in the upper 80s at night. I have kept my heating lamp on the chicks all day long/most of the night until 2am (when I go to bed). I worry about fire hazards and so I turned off the lamp and set my alarm for 7am to turn it back on. The chicks seem fine, though they are bundled together sleeping when I turn the lamp back on. They are under a week old. Is it harmful to turn off their lamp for this long of a period of time? If it is. Is it alright if I turn off the lamp and set a space heater in the mudroom for the time I am asleep?
