Is this enough ventilation?

One more thing, sorry.
Electrical issues, important for fire safety, and insisted on by our insurance company: all wiring in conduit or other chew proof cable, outlets exterior grade, and line to coop buried up to code. Essential! Rodent damage is real, and chickens may bite exposed wires too. Fires take out many outside structures, with the critters inside. Not anything any of us want to happen!

No electricity in the coop, Solar power, yes. Although, I plan on getting some by winter time so I don’t have to replace water every few hours haha

Hello fellow Kentuckien! Yes, we do get bad winters here i agree but cold is not your enemy its heat. You have got to cut a 6-8 inch vent along the side under your overhang and cover it with HWC.
Which way is your human door facing? N S E or W

My coop is elevated and open on 4 sides with screen (HWC) doors as well as vents at the top and my coop is 90 degrees inside.

The human door is kinda south west, more so south.

Don't cut into your framing! It looks barely adequate already. Agree with openings as recommended by @KyCoop, at least.
And remove the windows, use hardware cloth there instead. Maybe cover the lower sections in winter, at least on the windward side.
Those ready made louvered house vents can go up on each ends of the building, get big ones so there's air flow there all year, snow and rain won't get inside using them. Here we need another larger one on the west end of our coop, adding to the one that's already there.
More insulation in the roof, protected from rodent and wasp damage, will help with summer sun, which is worse than winter temps by far. Planting trees and shrubs for both shade and predator protection would be good too. Plan for your run, then plant outside of it.
Chickens were jungle animals, most comfortable under plantings, where it's cooler, and more bugs and worms can be found.
Is your structure up to code? Check about snow load/ ice load requirements where you live, if you didn't do that first. It wouldn't make it here in Michigan!
It's really cute and will be wonderful, with just a 'few' tweaks!
Here we've modified and added on to our coop three times over the years, all for those mythical 'free' eggs!

This was my husbands first big building project, so I’m sure not everything is perfect. Are there any ways I could add more support since it’s already built? I’ve taken the screen out of the windows and replaced it with hardware cloth that’s screwed into the coop under the framing around the windows. It’s kinda hard to tell in the photos, but there’s probably 1/2 thick insulation under the roof, what would you recommend I add? I’ve added some solar powered exhaust fans, one pulling air in, and one pulling air out. Both at the top of the coop, one above the man door and one on the side with the chicken door.

my husband and I have just built an 8x8 coop and I’m wondering if I’ve got enough ventilation. The top half of the Dutch door we are adding a hardware cloth screen so that I can keep the top main door open when it’s hot out and have more air flow, and the windows open. Is this adequate? I’m planning on getting a solar powered exhaust fan to put up at the top inside as well, but I haven’t found one I like yet, so if anyone has any recommendations I’d love to hear them!

I’m in western KY and our summers can easily be in the 90°s. The coop isn’t shaded during the day, but is in the evening, so I’m trying to avoid it getting super hot in here.

That is a really cute coop! I have something similar shape but not quite as nice as yours. But it has two doors on the front. You could use more ventilation for summer but it would be probably be very good for winter. However the fans will certainly help.
This is the inner door I have on my coop and the outer doors stay open most of the time, even in winter unless we have a storm or something. That helps a lot with the ventilation.

You man door is facing SW so not a lot you can do as far as adding vents there as its the side getting the most bad weather. You can add to the North side. Small vents. We don't get a lot of rain from the north.
You don't have to worry about snow load. Your roof has enough pitch on it to handle what we get. And in those weird times when we get 12 inches all at once you can shovel it off.

How is it attached to the ground? It's a very good size not likely to get blown over but you know how windy it gets sometimes not to mention twister weather. I think I would strap it down with it housing live animals.

Here we get fewer tornados and more snow!
Adding insulation to the roof will help in summer, as long as it's not inhabited by unwanted critters. And as long as your birds can't get to it either.
We have good shade in the south and west sides of our coop, and insulation in the roof still helps keep it cooler.
There will be dust in there! If dust will damage or interfere with your fan's function, watch it carefully. House grade fans aren't meant for barn use in that dust.
