We are in the final stages of finishing our coop. The hen house is raised 3' above the floor and the whole coop is covered (including the run). I was going to put wood mulch on the floor of the run but now am wondering if that is the best option? I was planning on shoveling it all into the compost pile whenever it needed to be cleaned out. Would sand be a better idea (and forgo the compost additions)? Opinions please!
