I have a plywood floor covered in vinyl, then pine shavings. I do a deep litter method and just turn it over until ready to be completely mucked out. I don't like straw as well becuse it doesn't stay smelling as nice but many people use it. Also, straw is hollow and can harbour bacteria inside of it. I also use shavings in the run and add to it every once in a while. When I throw the scratch out they dig around and keep the run turned over for me. My coop and run don't stink at all. I like to use Timothy hay in the nest boxes because it packs into a nice bowl shape for them and smells like fresh cut grass. Every morning a scoop out the big droppings and put them in a covered bucket to go into my composter or friends that want compost/fertilizer for their gardens. The chicken manure must be aged for a while to take the "heat" (ammonia) out of it before it can be used for gardening. This sounds like a lot of trouble but I can feed, water and tidy up in less than ten minutes in the morning. Good luck with your plans.
