That looks awesome!!! Dream chicken paradise!!! That setup is amazing!!!
One thing mine like is food skewers. They sell them on
amazon - metal skewers with chains/hooks on the end - you thread food onto the skewer, hang it in the coop, and the chickens fly up and peck at the food. Mine love this!
I'm in north Alabama, and I'll second what Dobie lover has said - You may need to remove that whole area above the clean out doors and frame it out with some hardware cloth over the entire opening, and probably do the same on the other side if you can. You'll need some good cross-breeze over their heads in the heat of summer. I did the calculations, and basically, the upper third of any enclosed coop would need to be hardware cloth open area to get enough ventilation over the chickens' heads for the southern summer heat. But since the weather is heading towards cool, you've got several months before this could be an issue - just keeping moisture out of the coop so they don't deal with frostbite on combs, wattles, or feet is all you'll need to worry about for winter - if you see issues, open more windows.
Mine live in a hardware cloth enclosed covered run year round (hoop coop / greenhouse frame hoop coop with a tarp over top), with no actual enclosed coop. They've been fine for multiple winters, including the really cold ones. I put some 6 mil plastic up on the ends of the hoop coops sometimes to cut down on the wind, and make sure there's no water that they can step in and freeze their feet, or their wattles, and mine have been fine overwintering "outside". They acclimate to the weather.
I'd recommend taking some boards and covering all the areas where you've secured the hardware cloth to the wood with a trim board - screw the trim board in place over the edges of the hardware cloth/seams. Kinda make it like a picture frame, where the wood sandwiches the hardware cloth "picture". Racoons will literally grab hold of the edge of the hardware cloth and pry it off of the treated wood, if you've secured it with staples or anything but radial washer and screws. Covering the joints so they can't get ahold of the edge to pry it up using the picture frame method also works. Dogs will get their teeth into any loose (non-taut) hardware cloth and pull also, but it doesn't look like you've got any of that, so you're good there.
I'm assuming you've got an apron under all that lovely mulch. If not, I'd strongly recommend putting one down. Mine extends 3 ft from my coop, and I've seen critters digging 2.5 feet away. That being said, most folks do about 18"-2ft, and it's fine.
Make sure that any openings or cracks anywhere into your coop / run (around doors, ventilation, nest boxes, etc) are less than 1/2" in width. The predators and pests that can get through that size area are usually small enough for the chickens to kill and eat, and there has to be some clearance for doors and stuff.
Enjoy your fun new chickens!!!!
