My girls would not go into their coop at night if they did not have the red light on. I guess this came from having the red heat lamp on all the time in the brooder. Anyway, the other night when I went out to close their pop door for the night and give them a little nightime scratch I decided to turn the red light off once I left just to see how that would react. I went out the next morning and everybody seemed ok. So I left it off. That night they went on in like it was normal. I guess I will save a little on the light bill.
