I need to correct my last comment, I didn't see the Hardware Cloth floor. They should have plenty of ventilation with a wire floor and a good vent over the door. Sorry for the mistake.You forgot ventilation, other than that, it's looking good. Are you gonna put the nest box in back where you left it open for easy retrieval of the eggs? Make sure to put your roosting bars/poles up higher than the nest boxes or you'll never get a clean egg from them. Down in GA in winter, you don't have to worry about the birds getting too cold as long as you have plenty of ventilation.
