I do also think you need more ventilation. An obvious sign is to wipe your hand on the walls or roof inside first thing in the morning, especially on a cold morning. If it's damp or wet, or even worse, dripping, then you don't have enough ventilation. The moisture is from your birds breathing and condensing on the surfaces. It's a sure way to end up with frostbite on toes and combs. They can put out a LOT of moisture breathing all night.
I would use the light to get them to come in, if they don't use the roosts then manually put them up each night until they start to. If they still are reluctant to roost, then redoing the roost layout may help. I really can't see them well, so just throwing that out there too.

Hello from SE MO. Poplar Bluff area. Where are you, around Willow Springs? My guess is the chickens stick their heads in to roost up there around dusk and hesitate to go in because it's dark and scary. Letting in a little ventilation and ambient light by adding some screened (or hardware cloth) openings along the top should really help, along with maybe replacing the steps with a ramp. Otherwise your setup looks really nice. As
