That is just tooooo cute!
Since you live in Florida and are concerned about the heat, you may want to consider the following in addition to a vent:
Dark colors absorb the sunlight and store it as heat. They heat up much more than light colors, so you may consider repainting it all white. (Try theese experiments: Put on a white shirt and stand in the sun for a about 10 min. , then switch to a black shirt and do the same. Another way to test this is to put identical thermometers in a black balloon and a white balloon (uninflated), set them in the sun, and check the temperatures in a few minutes.
Another suggestion is to place the coop where it is shaded most of the day.
Have fun with your stealth hens!
I live in central florida as well, I would paint it a lighter color. Also I would hang the feeder in the area under the stairs/roost area. I see a great place in the second picture, with the cute kid. I would put in some vents, for the air flow. It gets HOT, here. As you know, with no air flow, the humidity will get them. Mybe a corner fan that rotates.
I love the coop very much. I just use milk crates and outdoor carpet pieces for nest boxes. Easy to hose off if they leave you presents, that you can't eat!
