We use old wood shavings in the run after they've been cleared out of the coop. The run has a dirt surface so we rake the old shavings periodically to stir things up. The run's covered but the sides are just hardware cloth so in many places the shavings get wet when it rains. Mixing the wet with the dry by raking helps dry things out and mixes the droppings and shavings and helps the decomposition occur more evenly. We prefer shavings to nuggets because shavings break down faster and absorb moisture better. So the short answer is no, we don't clean poo from the run, but we do tend the run material with occasional raking.Curious to know if you all clean out poop from the run? I added pine bark nuggets and mix it around and it seems to be ok for now. Today, the edges of the run are getting muddy bc of the rain coming in from the sides. I'm reading to use pelletized bedding, but then it turns to sawdust. Are ppl picking out poop from it or just turning it often and letting everything just eventually become one with the dirt floor?
