Beautiful Chicken Coop Tractor. (Please share!) Chicken tractors allow a kind of free ranging along with shelter, allowing chickens fresh forage such as grass, weeds and bugs, which widens their diet and lowers their feed needs. Unlike fixed coops, chicken tractors do not have floors so there is no need to clean them out. They echo a natural, symbiotic cycle of foraging through which the birds eat down vegetation, deposit fertilizing manure, then go on to a new area.
