Large Size Automatic Chicken Coop Door Solar - Side Opening for Bigger

Our review of this large, solar-powered automatic chicken coop door finds it best for backyard flock owners who keep mixed-size or larger breeds and need a reliable, low-clearance solution. The single biggest reason to buy is the extra-large, side-opening design which lets bigger chickens pass freely without the overhead clearance issues of vertical doors, making it an excellent retrofit for many existing coops. It is practical, weatherproof, and offers multiple control modes so users can choose automatic scheduling, light-based operation, or remote control as needed.

Key Features

• Side-opening design: The horizontal operation avoids the need for extra overhead space, easing installation in coops with limited clearance.
• Extra-large opening: With an 11.42 in H x 8.86 in L aperture, larger breeds and mixed flocks can use the door comfortably without crowding or jamming.
• Five smart modes: Timer, light sensor, combo timer+light, remote control up to 15 m, and manual mode provide flexible automation or hands-on control when required.
• Dual power options: A 7 W solar panel plus USB charging keeps the unit running longer and gives reliable backup during low light.
• Safety and intrusion features: Anti-pinch obstacle detection reopens on obstruction and an intrusion alarm notifies attempts to force the door.
• Weatherproof construction: Durable aluminum housing is built for year-round outdoor use and typical coop conditions.

Who It's For

This door is aimed at hobby farmers and backyard poultry keepers who maintain larger or mixed-size flocks and need a wider pass-through than standard vertical doors provide. It is particularly useful for coops with low headroom where a side-opening design simplifies installation and avoids structural modifications.

Those who should look elsewhere include keepers with very small bantam-only flocks who do not need an oversized opening, or users who require an integrated automated feeder or advanced farm management network, as this product focuses on reliable door operation rather than broader system integration.

Frequently Asked Questions

Will this door fit a low-clearance coop?
Yes. The side-opening horizontal design is specifically intended for coops with limited overhead clearance, avoiding the need for extra headroom.

Can it run without sun?
Yes. The unit uses a 7 W solar panel for primary charging and accepts USB charging as a backup for cloudy periods or low light.

What happens if a chicken blocks the door?
The anti-pinch obstacle sensor reopens the door when it detects resistance and will retry closing once the area is clear, reducing injury risk.
