We just made our Bantam chicken flock a new run on the side of our house. It has a roof so little to no rain should get in. I really would like to do the deep litter method so we can use the compost for our gardens. I really am not sure what are the best materials. We live in Northern California so it is very moist here. Can anyone help me with what materials to use. Right now it has some bigger gravel and some dirt from where we had to dig to make the run.
