I hope you guys don't mind me asking here, but the photos have me wondering - what sort of rise/run do you find works best for your roosts? E.g., how far apart (including how far from wall for highest roost), and how much hight/rise between roosts, and how much headroom above the top one... I'm finishing my coop and trying to wrap my head around that, and I think I've read different things, and have gotten myself confused.
(This coop is for my Naked Necks, so, large fowl spacing needed...)
I have built this second one for better access and cleaning compared to the first attempt (all doors open on all sides), but it turns out I have some additional problem solving to do based on my modifications, so still working - but almost done! I promise to post photos once it's done!!!

I don't blame you for being confused. But I don't think it's rocket science. The angle dictates the spacing of the perches. The idea is to allow enough room so the birds above don't poop on the birds below. That also depends upon the size of your chickens. If you had few birds, and a lot of roosts, they'd all head for the top rung, anyway.
Some people solve the whole issue by having horizontal roosts. All the birds are on the same level that way, Personally I like a tiered roost, because it gives me one more piece of information about who is at the top of the pecking order in my flock.
How far top rung from the wall? How far is it from legs to the beak (plus a couple inches) of your biggest bird?
My opinion on the rise is that one rung should be just above eye level for a bird sitting on the lower one.
Here's a pic of mine from another thread. This roost is adequate for about 15-18 birds. Made from 2x2 (nominal) stock with the edges slightly (1/8") chamfered.
