Hi,
For bedding in the coop we use an initial covering of sawdust/fine wood chippings then lots of paper-shredding from friends, relatives and even the local school as its degradable can be put into compost bins and the brown lid council bin for composting, plus it soaks up everything and costs us nothing ! On top of that they get straw if it's really cold.
Larger 'poops' and wet patches are grabbed and 99% of the time removed daily (which takes less than a minute so why wouldn't you ?) so smells etc aren't an issue.
Floor of the coop is removable boarding and a slide out metal tray though as I say we can pretty much remove everything from the top by opening the 3 hinged roof sections so this all gets pretty much all removed and replaced over the course of a week.
The floor of the run is just soil (mud in this ridiculously wet weather, to which we add more sawdust, straw, hay etc when weather is dryer, to add something they can scratch away at, plus we throw mealworms, sunflower seeds and hearts, rice krispies, porridge oats etc etc which they LOVE !
Whenever we're away and they go back to the breeder we got them from (which they enjoy immensely) the kids and I totally clean the whole thing out, scrape out the run too and then spray the whole coop and run for mites etc which gives it all time to dry ready for their return.
They also get all the grass clippings from lawn cutting to kick through (but NEVER if you've used 'weed & feed' etc), and when we had 2 x 30ft conifers removed I asked to keep all the shredded trees for covering the run floor which the girls thought was heaven lol.
Hope this helps if anyone wants ideas ?
