Don't be sorry. I'm glad to know it's bad. I have to come up with a design to tell my builder guy, and I'm looking for inspiration/any good ideas that I can glean from existing coops. The premade ones all seem to be awful though.
So far, I know I want mine up on 2 ft stilts (to offer shelter and to have food/water available under there if I so choose), and the overall structure (not counting nesting boxes) should be 40 sqft or maybe 50 sqft. I'm currently planning on having 7 birds (1 Roo, 6 Hens), so technically I'd only need 28 sq ft, but you never know. I like to be prepared/flexible. Thoughts on this?
There will be a 15x18' enclosed run with a roof and a gate, made from D-knot no-climb horse fencing (unless ya'll have a better suggestion). 2' of skirting will line the outside of the run, with a 4' "L" of hardware cloth giving 2' of vertical protection against reaching raccoons and little animals and 2' of horizontal digging protection against coons, rats, and any other animals.
I want it to be symmetrical, so nesting boxes on both sides, maybe 3 per side. I'd like the back to drop out of the nesting boxes (rather than the roof opening up, for easy cleaning/egg collection) though please let me know if this is a bad idea for some reason. Also, tips on nicest nesting material that your girls like? Straw? More pine chips, something else?
I know I need the roosts higher than the nesting boxes, and I plan to have 2x4s for those. Maybe three or four of them. Stupid question: Is it better to have the 2x4s attached so the chickens sit on the bigger side, or turn them them so the skinnier side is where they put their feet? Right now my plan is just to have the roosts above most of the coop floor, and then a litter tray below that takes up most of the floor, leaving some space for a feeder and waterer that isn't in the bomb zone. As you alluded, my arms are pretty short, so even with a broom/rake I don't think I could reach the end. It would be great to just pull a giant pan out and dump it that way.
The back of the coop should have a keeper access door big enough to pull the litter tray out of, or maybe just fold down completely. I've seen some people who have one entire side of their coop drop down so they can just sweep the whole thing out. Having nest boxes on either side of the coop kind of eliminates this possibility though.
I plan to have an automatic coop door like this one (let me know if you know of a better one) because I have to leave for work very early in the morning (before sun-up) so I don't think they'd be ready to come out until after I leave.

I know I need vents higher up than the roosts. Is it better to have window vents so that they can be closed sometimes? I've seen some people that just have an opening and they attach hardware cloth over it to let air in/out. It rains so much here I feel like water would get in if I had a constant opening like that. I guess I need a way to reach them/close them. I'm not a tall person (5'4) so if my coop is too tall I might have trouble accessing them. I mean, there's probably ways around this problem, but I'd love any suggestions.
