A chicken coop built from wooden pallets mounted up on reclaimed 4×4 posts, filled with clay-straw slip, topped with a cob wall with bottle windows, then covered in chicken wire and plastered with a lime-sand plaster and turmeric and lime paint. Finished with shells. Interior features cob roosting areas. Roof collects rainwater into a chicken drinking water tub. Happy chickens in Southwestern Colorado! Built using almost entirely free/recycled materials. Let me know if you have any questions!
