I love the chicken art! And the hardware cloth! The windows are good, should help keep them cool. Can we have some pics of the clean out door? Since you live in Florida, I'm guessing you will want to leave it open during the day to help cool down the coop (especially with a hot metal roof) - maybe a drop-down netting cover to keep the girls in? You could use window screen, just roll it down and open the door for a breeze? You could glue some magnets at the bottom to keep it from becoming a chicken flap. I know it's more work () but I would add some more ventilation at the top of the building, as close as you can get it to the roof, since 'heat rises' and ventilation up their can pull the hot and humid air out of the coop. It will help pull smells out of the coop as well. Very nice!
