Hello! I am new to chicken ownership, and have been investigating flooring options for my chicken run. I am using the DLM for inside the coop, but not sure if that's best for run. The mud is obviously not going to work for anyone (esp chickens). Has anyone tried ground rubber mulch in the run? I read a lot of threads from folks in the UK using that. Easy to hose down, drains well, doesn't breed e-coli or other bacteria, etc. Just not sure. We are in Illinois, and we seem to get a lot of rain lately. Will rubber mulch work?
