Also, build it bigger! 4x4 is tiny and just won't work well.

Looking at your pics, I'd say the ventilation is inadequate. Little vents like that (especially when they're all at the top) don't allow enough air exchange. You want the air turning over as much as possible without actually blowing on the birds.I live in New Jersey and had frostbite issues on my rooster's waddles. Last winter he lost his comb tips. I have adequate ventilation but he still got frostbite so I put him and his three hens in our basement for a month until the weather got above freezing. You will have to play it by ear I think.
Sorry to hijack your thread arenner, but JackE, this question is for you!
I have three hens and a rooster. They sleep on the left side of the coop. There is ventilation above the front window, a little along the back where the roof line is, and when you walk in the people door there's an opening on the top left. Should I put a vent over the left side window as well?
I must be overdoing the cleaning, I replace their beddings once a week! Now in the winter I deep litter technique (two months) just topped shavings.Yes, the windows do open. I must admit these photos were taken just after my husband built it 3 years ago. It's worn and dirty now but still looks good. Thanks for the compliment JackE! Well my husband thanks you! Even when I add my 3 new ones there will be enough ventilation?
I clean out their droppings every day so it never smells. And I replace the shavings every other month or so. I have a sign on the coop that says "Spoiled Chickens Lay Better Eggs". Spoiled they are. Now if I can just get them to stop eating their own eggs . . . a topic for another thread.
