The Chicken Sedan is a shingled A-frame combined coop and run for urban hens as allowed by the City of Portland. It is movable and designed to fit over any of the owner’s raised planter beds thereby putting fertilizer where it ultimately needs to go. A combination of fixed and operable ventilation allows for a comfortable and healthy environment for the birds year round. Attention was paid to making the structure predator-proof including reinforced screens and lockable latches. All metalwork, including hinges and latches, is galvanized. Removable canvas shades on either side of the run control exposure to the elements.

Complete access to the interior for cleaning and collecting eggs is provided by means of four doors (i.e., sedan). Custom fabricated stiles and flashing ensure a dry coop in wet weather. The removable triangular door to the run is large enough to allow a person to crawl inside. A nest box hangs off the back of the coop and has a lid door designed for easy egg collection. The lid door has two lockable positions depending on the need for additional ventilation.

A garden hose can be connected to galvanized plumbing at the run to service an automatic watering bowl. A hook under the roost in the run holds a hanging feed at a comfortable height for the birds to minimize spillage. It is located near the run door for convenient refilling. A ramp between the coop and run is a draw-bridge door on a spring hold-open and is operable from the outside by means of a steel cable. It is generally left open except during extremely cold weather. Hemlock handrails were utilized for chicken roosts.
