For the DLM, how deep are the shavings for the summer months? Also, how much DE do you add to start off with? Thank you for any info

Thank you! I'll be starting the DLM tomorrow. Do I sprinkle the DE onto the shavings and then mix it all in or let the chickens do the mixing?

I would advise against use DE at all. I used the DLM successfully for a year (very dry, no smell). Then, at the start of my second year with it I added some DE and it ruined the litter. I noticed an increased smell and the bedding seemed soggy. I did some more reading and realized I'd just killed off all the healthy bugs/organisms that were composting the litter. (Just as people advise against bleach, so DE causes the same problem)
To cure the problematic DE layer I added dirt from an old compost pile to reseed the littler with healthy organisms, and then began adding litter on top of the dirt. It did solve the problem. Then, a few weeks ago I did my yearly clean out. At the top the littler was great (it gets up to 24 inches deep). I kept cleaning out and eventually reached the DE layer. That layer, about 9 months later, was still wet and smelly. Nothing had composted. But, beneath that layer the litter looked good again.
If I hadn't seen it with my own eyes I'd be skeptical, but I know it was the DE layer that didn't compost based on marks on the wall and how I know they correlate to the calendar.
One note: I keep reading people's anecdotes about how they do DLM and I see a correlation between those who use straw and DE. I have found straw to be terrible--it doesn't break down and instead holds the poop up, resisting being turned under. Those who use smaller bedding particles like pine shavings, leaves, grass, and even alfalfa seem to have a better result with their chickens naturally turning under the fresh poop as they scratch, thereby keeping the litter aerated so it can break down the poop.
So, if you have to use straw then I guess DE is a good idea, but don't expect any composting to happen. If, however, you can use bedding that is easily turned under and easily compostable I think DE undoes a natural process that eliminates smell and dampness on its own.
Thanks for all of the information on your DL method! I'm about to build a new coop using deep litter, and have a couple of questions. If I understand your setup correctly, you have a large coop, no run, and let your birds free-range? My plan is to have a combined coop/covered run under a single roof (similar to this) and do deep litter in the run all the time, and in the coop during the winter months. (I plan to have a hybrid floor that's wire in the summer, solid-with-bedding in the winter, for maximum ventilation in the warm months. Our Virginia summers are hot and humid.) I've gotten a lot of inspiration from this blog post: http://www.nwedible.com/2012/02/the-real-bounty-of-the-coo.html that talks about the amazing amount of lovely compost that deep litter creates.
So here are my two questions: you say that straw really doesn't perform well for you, but this blogger swears by it for her run. Is it the difference between the run vs an indoor coop? Different climate? Second: some DLM users rave about the finished compost coming out of the coop. Others say that their wood shavings come out looking brand-new-- so obviously they *haven't* composted, right? What's the difference? I want compost, not still-brand-new-after-6-months shavings! Is it the DE use-- maybe people using it have fresh-looking and -smelling shavings, but aren't getting any microbial action?
