DLM, for two deeply different reasons. 1) I'm lazy and interested in doing infrequent, heavy work in order to be able to do the work at my convenience. Doing weekly turning of the litter and annual raking out with removal of 80% biomass works for me. 2) The idea of promoting and working with tuning an active living biome of the litter that is complex and healthy, makes sense to me. And there's lots of evidence to support it.
Therefore, in sum, I put 6+ inches of pine shavings inside the (well ventilated) coop and rake it up every once in a while to keep it dry. In the (very large and much less managed) run, we put all manner of interesting carbon including sticks, old wood chips, old leaves, some compost. The birds are encourage to scratch around and turn everything. It has worked well for 4 years and provided good compost for my husband's garden.
