How does my coop look?

[Sussex19]

So the coop can hold roughly 8-9 standard size hens (calculated at 4 sq ft/0.37 sq m per bird). You have enough ventilation right now for about 3-4 birds (1 sq ft/0.09 sq m per).

That sounds about what my common sense was telling me, but I always got a bit lost in the maths so thanks for that. And that does sound like some more ventilation is needed, as in the moment there's 5 hens and a rooster.

Given your temperature range, increasing ventilation would be recommended. I'd consider opening up the triangle above where the vent currently is, and do it on both sides if possible. Top hinge it or enlarge the roof overhang so it helps protect from the weather.

I think we can do something like that!
And I think both sides is possible, although I'll have to see what my dad thinks.

So it's 2 roosts? One against one wall, another across?

There's a main one running down the left hand side, a short one across the end, and a fairly low one running down the right hand side. Although that one doesn't get used very much.

I can't quite make it out? What are the lines in the coop? I feel I'm being rather dense.

The blue lines are the airflow through the vents at the top and bottom of the roof slope. Here's the full article: https://www.backyardchickens.com/articles/repecka-illustrates-coop-ventilation.77659/

All the other pics make sense,(and its a great article) but I still can't quite get my head around this one.
The main black line around the out side is the coop walls right? So what are the black lines in the coop? But I think I've got quite a good idea of whats wanted, so you can just ignore my thick headedness.

That's the cover picture for the article. The black square around the outside is the whiteboard that Repecka is drawing on. The two black vertical lines are the walls of the coop and the slanted black line is the roof.

I'm not much of an artist.

Oh I see now!
It just didn't occur that she was drawing on something!
And you're a better artist then me, I'm hopeless.

What are the cages for on the ground?

For a single slope roof this is what you want your airflow to look like:
