I am new to chicken keeping....so What is DE? I saw many references to it? For those people referring to the deep method? How deep is deep? No one even mentions a depth? As far as poop boards are concerned; how often do you clean them? Would you recommend them? Lastly, everyone talks about using pine chips. What about chips from other shreded trees such as Birch, Willow, Pine, Cottonwood etc? And do these have to be fully dried before use? I know for landscaping/gardening purposes it is not recommended using wet/unseasoned wood chips because it robs the ground from oxygen as the chips break down. Currently I use straw. About 4-6 inches of it. But I have a big coop with about 10 normal sized chickens and about 15-20 bantams. The hay gets packed very quickly. I am trying to figure out a new method for bedding. Too much dust, smell and poop to clean now. I'm in Alaska if that helps anything. Everything is expensive here. Just curious Tnx!
