I have a 10 x 12 coop with a large run: It was all made out of old telephone poles and stuff we had laying around the yard The wood is not pressure treated... how do I go about doing a real thorough cleaning and what do I use. My DH said not to use the pressure washer because the wood will hold too much moisture. Should I just scrape everything down (it needs a good cleaning) and maybe sprinkle some DE? Ive been changing the pine shavings and cleaning out poop from under the roosts, etc. weekly since Ive had the chickens. But some of the poop is really stuck and Im goign to need to get out the scraper. Should I be doing more than that?
