I use the DLM, but my coop is large with lots of ventalation. The coop is 14x24, the main pen is 12x12, and I have 2 7x8 breeding pens. I throw some scratch in the litter daily and the chickens keep it well turned, I have never had a problem with moisture or odor. I use a mix of shavings, shredded paper, and straw, and just add more of one or all as needed. I did just get some DE from TSC and added some to the litter, but didn't see that it made any difference. I do like to use the DE in their dusting area. My coop is not insulated, and I do not add heat in the winter. I do have heated waterers for each pen. I have a covered run area for each pen and the chickens are able to go out year round, and they do what I call modified free range all summer in 1/4 acre fenced pens.
I have really, really wanted to do the deep litter method but keep reading altering information on what actually to use to make up the litter. It's got to be more than just shavings and DE, right? I read one article that was so complex and it has kept me from actually going for it. You add the shredded paper, straw, or shavings as it begins to feel moist in there to you, Azriel? What about smell - how bad does it smell? I wish I could remember what the article said to add to the litter when the ammonia smell got strong - it seemed really odd to me. My coop is 12 x 60 feet and I am really getting worn out on cleaning it - would love for the deep litter method to work, but don't want to screw up a good thing by doing it improperly. Is there a point in time when the entire place has to be deep cleaned and the process begun over?
