I would love to try this, but I am afraid of the coop getting too hot in the summer. We have had a killer summer this year in Georgia (though very dry in my area which is unusual) and I would hate to add heat to the coop when nights are already in the 70's. Also, I have a dirt floor in my coop, so can I still do the DLM? My coop design is such that I have sufficient ventilation in my coop but not a deep area in front of my door.
Yep...it actually works very well in the south, where it's humid and warm...that speeds up composting. Just make sure you have some really good airflow in the coop at all levels(BIG windows/openings) or even fans.
Don't stir the litter, cap it off with dry materials when it becomes too moist and let it cook down. I'd avoid pine shavings unless you are composting too fast and need to bulk up and slow down the composting a tad. They take forever to compost, don't absorb well and put off a lot of ammonia as they compost....I'd use them sparingly if you want some real, working compost going on.
To avoid too much heat in the composting litter, don't add any green materials like grass clippings, hay and such. In a humid environment, you'll want things with different particle sizes(so don't use all one kind of material) so that you can provide air pockets in the litter pack, and you'll want some woodier materials like leaves, a little straw, pine needles and cones, woody plant stems, corn stalks, aged wood chips(not shavings)etc.
It will actually work better on a soil floor, so no worries there.
Rosemarie1 is in MS and she uses DL, though I think hers is mostly pine straw...she loves it, though hers seems to compost rather quickly for her.
