How does my coop look?

[Sussex19]

I was wondering what the coop experts on here think of my coop and run.
Particular in respect to how many chickens can it take, and the ventilation.
The chickens do go out most days into a much bigger run.

I see that you are from NSW Australia. What are your hottest and coldest temps? That can make a huge difference in the amount of ventilation needed and where it is located

Thanks for the reply!
My dad built it for me, and we didn't really know what was wanted, so all suggestions welcome. Would it be better somewhere else?

Ventilation should be above the chickens heads when they are roosting

What are the cages for on the ground?

Sorry I should have said, they are temporary enclosures for broody hens.
The hens are in the nesting boxes and the cages keep the other hens out.

We'd need numbers to best calculate - i.e. coop floor space minus nests, run floor space, length of roost, total ventilation that's open 24/7.

If you look at the photo from the outside, would it be better if the vent was where the panel above the vent is now?

Higher would likely be better but the best gauge of draftiness is to take a lightweight ribbon/yarn/etc and hold it at roost height on a typically windy day, and see what it does. Moderate or little movement is fine. It the wind is blowing the ribbon around noticeably, then yes that's a draft at roost level.

Here's the measurements, they are all a bit rough though.
The main floor is 1.35m by 2.40m. Hight on the lower side is 1.40m and on the higher side is 1.68
The vent is the same length as the floor, so 2.35m and about 15cm wide.

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).

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.

Oh and I forgot the roosts, but they just go from one wall to the other, as seen in the pics.

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

Floor space is slightly reduced in the moment due to those broody enclosures.

Thanks for the links!
My problem is that I'm not very good at looking pictures of coops, and then adapting those ideas to suit mine. Can you make any actually suggestions of how I can improve it? It is a bit drafty in the moment I think.

It's a bit late in my evening after a long day of work to do math so I'm just going to trust @rosemarythyme's calculation.

Do your winter winds/storm winds come from a consistent direction? If so, you might be best served by turning your leeward wall into all wire so as to turn your coop into an Open Air design.

I can't see the entire roofline in the photos. Is it peaked or a single slope?

Getting ventilation at the very top of the roof is desirable in a hot climate because it lets the heat out and draws the cool air up from below via the chimney effect.

Looks pretty good. Agree with @rosemarythyme dimensions would be great.

My only concern is the that wall ventilation looks to be directly across from roosting bars, which possibly could be a concern

Ventilation should be above the chickens heads when they are roosting

Yep, above heads. When there is a draft and it ruffles feathers is when they lose heat and is probably just not comfortable regardless if freezing cold or just cool.
