It sounds like your run doesn't get enough sunlight in the winter, which can only be fixed by exposing it to the southern winter sun. If your run is draining like you say and there's no standing water, adding sand won't make it drier. It just isn't getting heat from the sun so it feels more damp and cold.
Ventilation in the coop should allow air to circulate upward and out. You need openings at the top and bottom.
Good luck figuring out how to fix things.
