Good luck finding materials to build your coop (don't forget wooden pallets, they're usually free!).
Be sure and make your coop/run predator proof. Build it like Fort Knox and use hardware cloth rather than chicken wire as there are just too many predators that can either tear through chicken wire or squeeze through the openings in the mesh. There is a good article at http://www.the-chicken-chick.com/2013/07/11-tips-for-predator-proofing-chickens.html on predator proofing your chickens.
I would definitely recommend building a slanted roof to keep the birds from nesting on it and pooping on it.
Keep up the dream and finish the job....
