Stop Losing Chickens to Preventable Predator Attacks
Every chicken owner knows the heartbreak: walking to your coop in the morning to discover your favorite hen is gone. Predators cause 80% of backyard chicken losses - and it usually happens because someone forgot to close the coop door just one time.
The Coop Tender Difference: Engineered for Real-World Threats
Most automatic doors use cables and pulleys that predators can defeat. Raccoons have opposable thumbs and problem-solving intelligence. They will figure out how to open cable-driven doors.
Our steel worm drive creates a physical lock that cannot be forced open by any predator - not raccoons, foxes, coyotes, or even bears. When the motor stops, the door is mechanically locked in position.

Frequently Asked Questions
How predator-proof are automatic chicken doors?
Coop Tender doors with steel worm drives are mechanically impossible for predators to open. The self-locking drive system means raccoons, foxes, coyotes, and even bears cannot force the door open once it's closed.
Do I need internet for the door to work?
No - the door operates automatically using light sensors or programmed schedules without internet. WiFi connectivity is optional and adds remote monitoring and control capabilities.
How difficult is installation?
Basic installation takes 2-4 hours for DIY enthusiasts. We also offer professional installation in most areas for customers who prefer expert setup and testing.
What happens if the power goes out?
Battery backup systems provide 5+ days of operation during power outages. Solar-powered systems operate indefinitely without grid electricity.
Can the door handle harsh winters?
Yes - Coop Tender doors operate reliably from -20°F to 185°F. Freeze protection features keep doors closed during dangerously cold weather to protect your flock.

Standard 12"×12" works for most flocks. Large breeds benefit from 15"×15" sizing. Our sizing guide above helps you choose, or call our experts for personalized recommendations.
