I know this has been discussed elsewhere, but I didn't find exactly the answer to these questions, so I will post them, and hope either for good advice, or to be pointed to where the answers already are...
I live in Missouri, where it will be below freezing a fair amount, but probably rarely as cold as single digits F. I have 4 hens (buff orpington, barred rock, partridge plymouth rock and New Hampshire Red) in a 6 x 10 uninsulated coop. It has vents below the eves on the North and South sides. The hens ignore their roost, and roost instead on a shelf way up in the northeast corner of the coop, right in front of the vent--but on that side, there is some shelter from the wind by the overhang of the sloping roof. There is a big window on the south side which does warm things up on sunny days.
I am thinking of using a deep litter method for the winter since I have read that that keeps things warmer.
Does it sound like my girls will do okay without supplemental heat? Should I remove the shelf and MAKE them use the roost, away from the vent? Should I cover the vent. I have read that they need plenty of fresh air, even when it's cold. Maybe I could block the north side vent, and keep the south one open.
Also, I had pretty much planned to let them into their run every day. Is that okay, or do they need to be kept in at a certain temperature?

Our coop is raised, smaller than yours with just one roost. Pecking order seems to determine which hens rate the roost, but the others contentedly pile into the nest boxes together, covering their feet and heads with downy fluff. Their little coop has a deep litter base so they can always nest down in that as well, and some do. I stir this daily so they do not overnight in messy conditions. Our hens have the choice of retiring to the coop at night or going through their chicken yard pop door into a larger pen inside our metal barn which has saw horses for roosts, multiple nest boxes, and deep litter. Usually fifteen or so elect the coop while a lesser number sleep in the indoor pen. Our little homemade coop is not air tight by any means though I've caulked most cracks. We have a four inch vent strip the length of the coop (@ 6') above their nesting boxes. I block most of this is the deep winter, but always leave some space for air circulation. Another small vent is on the opposite wall, up under the roof overhang. This too I partially block in deep winter. I worried terribly about them last winter, but my DH reminded me that they wear down coats full time and stay rather toasty unless we get into gale conditions. Then we run them all into the indoor barn pen. I've not seen any signs of frosbitten combs, wattles, or toes, so our system must be okay for our conditions here in mid MIssouri. Best wishes with your chickens! ~G
