Here is a link to pat's ventilation page. Also check out the cold weather coop page link.

For now they need only food, water, predator protection, and a place to get out of the wind and rain -- and ventilation. You have til winter to deal with cold weather issues. Even roosts are not a necessity now, and obviously nest boxes aren't. Actually, nest boxes are a hassle if you install them when they are young as they tend to get in the habit of sleeping in them -- which you will not like when it makes your eggs poopy down the road. I see you have 3 perfectly good white plastic thingys for nest boxes. I'd put them up in the garage for a while!
Short roosts when they are young are nice, gives them something to play on and helps them learn, but they may not start roosting for real for a couple or 3 months, either.
They won't freeze and they don't need heat. They will need a wide roost when older so they can cover their feet well and keep their toes warm (like the wide side of a 2x4.) On bad nights you may want to put some Vaseline on their combs for frostbite protection. Other than that, they grow their own down coats and will do well.
You'll see from Pat's pages that your winter enemy is not cold but warm humid ammonia-y air, which they produce themselves. Read up and plan your winter hole in your shed for ventilation -- lots of time for that.
Also, chickens love a window near the roost they can look out of. Doesn't even need to open.
