The Chicken Hilton, our 13x24-ft main poultry house. In winter I block all windows with plywood (as shown at the extreme right), but the solid front doors remain open except in the nastiest weather. Inner wire-on-frame doors can be latched closed (as in the far left doorway) to confine the birds while allowing maximum airflow and sunlight, or latched open to give the flock access to winter yards protected by electronet fencing.
