I cleaned my chicken run and then added sand. I use a metal kitty litter scoop to clean the poop several times a day. Hardly any smell from my 19 hens! I use pine shavings in my coop and shavings and hay in the nest boxes. I also have poop platforms under the roost that I clean every morning. Only takes about 30 minutes in the morning to clean and feed. I take all the poop to my compost pile.
