YES GEORGIA-HUMIDTY IS AWEFUL.I PLAN USING HARDWARE CLOTH OVER THE WINDOWS IN THE SUMMER AND CLOSE THE WINDOWS IN THE WINTER.I WAS GOING TO HAVE A SPACE JUST UNDER THE ROOF OVERHANG OPEN COVERED WITH HARDWARE CLOTH ALL THE WAY AROUND FOR VENTILATION.IWILL ADD A HEAT SORCE IN THE WINTER AND MAYBE A FAN IN THE SUMMER.THERE WILL BE CROSS VENTILATION WITH THE 2 OPPOSITE WINDOWS.
First, it is considered shouting when you use ALL CAPS. We all did it at first, and someone had to ask us to turn off the caps lock, so don't take it personally, just trying to help
I would leave the windows open all year. Maybe storm shutters, or just extend the roof out more. Chickens can handle the cold, they can't handle dampness. I'd go with a fan definitely. The heater should not be necessary. Maybe a heater for your waterer.
The deep litter method would work great on concrete and has a lot of benefits. It will even heat the coop a bit in the winter. Sunlight is important with the DLM, and you should try and have at least 1 sf of window (in the South and East sides) for each sy of floor space.
A good sized run can make up for a lot. I agree to try and keep any shrubs or trees around as shade will be very appreciated by the birds.
