We built a second version of a chicken tractor for the incubator champion chickens and moved them outside to the grass.
The design is heavily influenced by the ubiquitous Joel Salatin builds from Polyface Farms. Since we had a truck bed liner salvaged from a neighbors trash, we used it for the canopy in the back.
Every day this gets moved to a new patch of grass, the food bucket is checked and the water is managed. Protection from predator and wandering off while befitting from the pasture and fertilizing the grass. Wins all around.
