Being in the Pac NW, I have LOTS of experience with mud. I have had excellent success using wood stove pellets. You can buy the type for horse stalls, use which ever is cheaper and has no added chemicals. I use the pellets all over my farm. As it absorbs water, it turns to fine sawdust. Very absorbent and for some reason doesn't really mix into the mud. I like the pellets much better than shavings.
Good luck to you.
