Automatic chicken coop door uses a motorized aluminum panel, ABS housing, and solar power unit so the door can open and close without frequent USB charging. The 14 x 12 x 4 in housing and 10.6 x 14.3 in cut opening work with many backyard coops and outdoor poultry houses. Light sensor mode opens and closes with sunrise and sunset, while timer mode follows your schedule. Remote control mode works from 98-131 ft away, and manual buttons on the housing provide direct control at the coop. An anti-pinch function helps prevent chickens from being trapped as the door closes. The aluminum panel is built to handle -31℉ to 140℉ for outdoor use, and the internal battery can power operation for up to 30 days after a full USB charge.
