Yes we are adding vents to each peak, we might add windows in the door, only place big enough, haven't decided yet, maybe a skylight. Till then I will supplement with indoor lighting. We have 12 chickes in the living room brooder as we speak. 6 Golden Comets, 4 RIR and 2 Black JG's/all pullets. It is linoleum, couldn't find glass board to put down. The run will have a 10x12 area covered with metal roofing and another 10x12 area uncovered.
