I grew up on the farm and so very familiar w/ barnyard smells but I am trying to be considerate of my neighbors and the nearby business. What is the best way to keep the odor to a minimum and keep the run and coop clean? I saw a great idea to put a shelf of sand or "Stall dri" under the roosts... I am leaning toward a linoleum floor... our coop will be in a green belt that is part of an existing dog run enclosed in cyclone fence. The total space is 80' long by 12' wide under fir trees. How much area should be sectioned off for the chicken yard? The plan is for an 8'x4' coop for 9 hens. Thank you!
