Cedar mulch outdoors in a run isn't going to do any harm.
You may have to try a few different ways before you settle on what works best for you. It is even possible you may want to use different materials at different time of the year. Don't be afraid to experiment as long as you are prepared to keep a close eye on things and change it all out if signs develop of problems
Good luck, have fun,
Pat
