Drainage is essential. If any standing water gathers(after clearing out the mess) either add clean dirt to raise level and/or dig trenches to drain area.
Wood chippings are coarser than most bagged mulches.
My runs have semi-deep litter(cold composting), never clean anything out, just add smaller dry materials on occasion, add larger wood chippings as needed.
Aged ramial wood chippings are best IMO.
I started out with wood chippings stored at a buddies for about 6 months before adding to my runs.
