My coop sits off my lawn with the whole side of my coop engulfed in woods and shade of a little hill. My south sun is so-so. Great for Summer and keeping cool..not so great for a little solar heating in the winter.
Not everybody has built that style of coop that JackE has. And that coop works pretty great for winters yes. Most people have a gabled or a a simple slant in their roof (to me the simple slant is probably the best and I wish I had it) So then you need to figure out how to deal with the relative humidity for your area vs. the cold. I'm just putting it out there that there is no one answer for all coops and chickening style.
Considerations for breed type, what your using your chickens for utilitarian or show, head space in the coop, ventilation, number of birds, size of the coop....etc etc.
Research it out folks.
