Frequently Asked Questions
What makes the Certified Humane door different from smaller sizes?
The 21" × 18" opening is specifically designed for large waterfowl (turkeys, geese) and high-traffic commercial operations. It's 40% larger than our Extra Large door, allowing multiple birds to pass simultaneously. The heavy-duty motor and reinforced worm drive handle the increased door weight and frequent operation required in commercial settings.
Can the Certified Humane door handle full-grown heritage turkeys?
Yes! The 21" width easily accommodates even the broadest turkey breeds including Broad Breasted Bronze toms weighing 30+ lbs. The 18" height provides clearance for turkeys with their heads up naturally. Customers with heritage turkey operations report their birds walk through comfortably without any hesitation or stress.
Will this size work for a flock of 80+ chickens?
Absolutely. Many customers with large chicken flocks (50-100+ birds) choose the Certified Humane size specifically to handle morning rush hour when all birds want to exit simultaneously. The wider opening prevents bottlenecking and allows 3-4 chickens to pass at once versus single file with smaller doors.
How much power does the Certified Humane door use?
Despite the larger size, the door is extremely energy-efficient. Electric models consume less than 1 watt on standby. Solar-powered models operate indefinitely with proper panel placement. The motor only draws power during the opening/closing cycle twice daily. Annual electricity cost is typically under $2.
Is the door strong enough to prevent predator entry?
Yes. The 5/8" steel worm drive locking mechanism is the same predator-proof system used on all our doors. When closed, the door cannot be forced open by raccoons, bears, or any other predator. The larger size actually uses a reinforced version of our standard worm drive to handle the increased door weight while maintaining the same impenetrable security.
