I live scarcely 1 mi from a woodmill which generates mountains of sawdust and latilla shavings (bark peeled from sapling poles). I cannot haul truckloads home fast enough to keep the owners happy! I shovel about 3 parts sawdust to 1 part shavings into the coop. Straight sawdust compacts too much, while straight shavings doesn't absorb or clump, but the blend seems easiest to manage while staying somewhat aerated.
The rest of the latilla shavings I spread as mulch wherever my O horizon's non-existent, gradually restoring the soil fertility one load at a time...
