I can take more pictures if needed, the inside has linoleum down ontop of the plywood floor then sand ontop of that. I have a strainer similar to this and a cat litter scoop that I use to scoop all the poop into a plastic colander.
Got five Silkies and one Mille Fleur from TSC back in March and by the end of this weekend ill have the coop finished. I need to paint a little bit more, fill in the trenches, get sand for the coop, and little stuff like that.
