I just added about 6 inches of pine chips to my 8x12 uncovered run. Girls aren't too impressed as they loved digging around in the dirt. I am in Florida and where I live we have very little grass or leaves. That being the case, what should I add periodically to the run? Just keep adding pine chips? Also, the run is attached to a coop and smaller run. Coop is elevated with the run below. That has become a mixture of dirt and chips. It is currently very dusty in there. Hard for me to get under there to do much with it. Not sure if I should try throwing pine chips in there and maybe moistening with some water to get the dust down? They love laying around in the dirt so I'm not sure if it would be ok to just keep this area dirt....but then how to maintain all the poop??
