Am I missing anything?

Oooo, I like the idea of the trim boards. It would match the trim on the coop. I'm not sure anything could actually get ahold of the edge of the HC. I stapled every 1 to 1.5 inches. I can't even get a screwdriver under it without a lot of work. These aren't your typical staples. They're construction staples.

I'll definitely be looking at better ventilation come spring. For this winter, I'll just monitor and make corrections if I find it necessary.

If they're the kind of staples you hammer in place, you might be fine. You never know exactly what predators will do - it might work out fine. But I'm over-run with raccoons and all the predators, so I over-prepare pre-emptively. Good luck!!!

They were installed with a pneumatic nail gun. Hopefully that will be strong enough. The only real predators in our area are possums and hawks. I'm more worried about my Cocker Spaniels harassing them. I'm thinking I might have to install lattice on the bottom half of the run just for a visual barrier.

With the run being fully predator-proof, provided the hardware cloth on the walls is properly secured, you don't need to close that pop door and it will serve as your low fresh air inlet ventilation.
That is the way I have my setup and I never close the pop door.

I love your setup. I wish I had the space to do something so grand.

Here's some of the interior run details. I have a 12-gallon cooler for the watering cups. There's a PVC feeder supplied from the outside to make it easy for whoever watches our chickens when we're vacationing. There's also a hanging bucket feeder that they have to peck at the dangling rubber stoppers to get food/treats to drop out. There's also 3 treat feeders on the various perches (each attached in at least 3 places), along with mirrors in different spots so they can admire how they look -- LOL

All I gotta say is that is a great first coop and I can tell you did a lot of research.

Don't forget to add a container for grit. First chick grit, then regular grit. And once they start laying, a container for oyster shell, especially if you're feeding all-flock instead of layer pellets.

You may want to add a no-tip dog bowl beneath your treat feeder that drips out the bottom to catch what falls. Chickens are notorious for wasting food.

A fun enrichment idea - You have a fair amount of sun - consider a grazing frame. It's where you put a frame of 2"x4" with hardware cloth stretched over top of it directly onto the ground inside the run. You put wheat grass, or any grass or grain on the ground beneath it, water it good, and then when it grows up through the hardware cloth, the chickens eat what they can reach. It's like a garden/yard bit that they can't destroy. Might consider securing it with landscaping stakes so they can't dig under it or turn it over.

I didn't realize there's different kinds of grit. I'll have to find some for chicks I guess. I have regular grit and calcium in dispensers by the door. The bucket feeder only drops maybe a teaspoon of food/treats at a time. It's just so they have to work a little bit to get to it. I'll definitely be adding a grazing box next spring. This winter I plan to sprout wheat grass and give them sheets of it to supplement their diet. Not much other than ivy and blackberry brambles have ever grown in the area where the run is.
