I'm planning on bringing my dozen babies inside tonight as it is supposed to go down into the low to mid 30's. They've been in the coop since I got them a week ago with a heat lamp and 250 watt red bulb (changed from a white bulb when I realized they were pecking each other). they will be in one of the bathrooms. Do I need to have the red light on for continuity and heat (not as close to them as outside) or will they be fine without the light in the house? These are my first babies, can you tell?
