I framed out the coop and run and enveloped the whole thing in 1/2" hardware cloth, the best deal I've found is at Portage Bay Grange in the University district, they have the thick galvanized stuff and sell it by the 4'x48"x100' roll or by the foot. I use decking screws and washers as turnbuckles to get the HW cloth nice and night before nailing down with Fencing nails/"U"nails. for the roof I use the corrugated, fiber glass reinforced, translucent roofing. Lowe's has the best option in this regard. I like the translucent version because allowing light in during the winter really helps them get through the winter up north here:

for the Litter, I've experimented quite a bit and they seem to do best on a rock/pebble free dirt base that is a bit sandy. I have thrown in features, stair stepped due to slope, added a chicken swing, places to fly up and rest etc. I do a variation of the deep litter method. if the droppings stay dry and you have enough surface area per bird (which you do), the droppings get broken down and eventually get turned into the substrate and eventually turn to dust. this happens at a rate that is adequate to keep the ammonia/smell to pretty much zero and the birds are happy, and requires removing some of the substrate about once a year, just to keep the level down. for the inner coop/roost, I use a good 6-8" of "mulch" (dirt/wood chips/loam). the hens spend some time every day up in the inner coop turning the soil and that keeps it mulching and reasonably good air quality with the side benefit being, virtually no maintenance, maybe once every 3-6 months swapping out the substrate and composting it, which makes amazing compost for the garden and fruit trees." my roost/inner coop is up off the ground and lined with shower stall liner for easy cleaning and wood protection.
for waterers, I find it's important to keep things dry and clean. the brand waterer that has the best nipples and the best UV transparent bucket (for easy monitoring and no algae) is this one:
http://www.atwoods.com/poultry-feeders-watering/cheery-chicks-chicken-kooler-35-gallon.htm. you can pick it up locally at
https://www.kisfarm.com/, which is worth a visit if you have never been, it's kind of a mind bogglingly cool farm/store. I made some calls around and got to the guy who designed the chicken Kooler, he claims to be the originator of the water nipple system for chickens in the US, IDK if that is true, but he says that he found the best nipple waterers that don't leak and most everyone else uses a cheap version that leaks, hence the development of the Horizontal version. In any case, I've used 5 different brands/styles of waterers (a couple brands of nipple waterers) over the years and this one has been the best, no stink and muck under the waterer, mine stays dry and I have several of them (I grow out meat birds twice a year to feed my family of 4 as well as have 6 egg layer hens). he recommended using this water heater
https://www.amazon.com/Allied-Preci...-fkmr0&keywords=heated+bucket+poultry+drinker . it has worked great through the coldest part of the winter here. if you don't protect the nipples from freezing, they will eventually start leaking.
well, there you go, there's my brain dump, just figured since you are local that I would give you more than usual detail. this climate has it's challenges, it's dark, damp and cold for the fall/winter/spring months. here is my coop for reference, i used retaining wall bricks because of the steep slope, which I needed to terrace and hold back anyway.
