I've just moved my chickens into their coop and am finishing up their run right now - I currently have about a 2-3 inch layer of pine shavings on top of vinyl covered OSB in the coop and a poop board under the roosts to catch as much as I can. I have been reading about Deep Litter Method and it seems like it would only work with ground contact. I haven't decided what I'm doing yet in the run as far as bedding or leaving it dirt - although we have heavy clay soil, it had been grass before all of my digging around and comings and goings - now it's mostly just packed dirt. They will get some level of free range every week in a tractor I'm building and DW is a chef, so they get regular kitchen scraps coming home from the restaurant - essentially whenever the bag in the fridge is empty she brings home more - so they get a lot of variety in their diets as well as an afternoon snack of kudzu every day - so while I'd ideally like a grassy run for them, I"m not sure it's in the cards and they get greens from other sources. So questions: 1) If you use DLM in your coop - does your coop have ground contact? Does it work without? 2) If you have a dirt run floor, do you use bedding on it? 3) Does anyone use DLM in their run as well? 4) Any other wisdom from the ether on bedding and deep litter? Some pics: Construction phase - but you can see the hard dirt situation here.
