When I go out to check them before bed, they are all laying on the floor lined up against the wire looking outside. (I don't think they are cold though...they just like the breeze that comes through. They like to get some time in before I close the lower flaps.) They have a roost...some like it, some aren't so keen on it yet. I've been giving them some dark at night, then I turn a light on around 10:30pm for them. They all get up and chase bugs when I do this. If I want to keep a little light on them for a bit longer, what wattage bulb should I be using? It is in the 70's at night here. Right now I have a 75 watt in the house.
