Going into this fall/winter season I'm noticing my coop is really dark inside all the time. We live in a wooded area as it is and now it's the rainy season so there are many gloomy, rainy days sometimes for days in a row. So my two part question is this...do I need to leave a light on for them all day long every day? And also I've been leaving two heat lamps on for them 24/7 for light and warmth. Temps have been getting down into 30s at night. Are the heat lamps necessary? (They are 3 months old)
