Recommendation by Rob Ludlow

As the co-author of “Chickens for Dummies” and owner of , the largest and fasted growing community of chicken enthusiasts in the world with over 50,000 members, I have come across many products for every aspect of raising backyard chickens.  One of the most interesting products I’ve looked at extensively is the automatic chicken door. I’ve seen a plethora of different designs and even had my hand at a homemade model for my own use. Unfortunately many of the designs (including my own) had issues that needed to be addressed. When I happened upon the Pullet-Shut Automatic Chicken Door I was very interested in their approach.

In a word, WOW. It lived up to, and exceeded my expectations. From my experience, this is the best door on the market and has some very exciting features that really make it unique: Start with the frame. The frame of the door is made from solid 7/8” aluminum. Almost all the other models I’ve seen use wood that tends to warp or bendable weak hollow aluminum or rusting steel. This frame holds the door square and true no matter where or how you mount it. Next is the door. It is aluminum clad and won’t warp, bind, rot, rust, or fail due to UV rays. And the door has plastic edging, to prevent injury to a chicken’s leg or neck. Also, many of the doors on the market use a string to pull the door up & let it down… not very critter proof (especially when you factor in how crafty and strong predators like raccoons are). This door is directly driven by a strong motor and the spaces between the door and frame are so tight that a predator would have a hard time getting any claws into the door let alone pulling it open.

Being a bit of a geek I was especially impressed with the electronics driving the door. Most of the doors I’ve seen have awkward systems to control the open and close positions, clumsy lamp timers for setting the open/close times, and a slew of other issues that are cleanly resolved and integrated into this super simple design. It took me about 10 minutes to install the door and about 15 seconds to set the open/close times! The door has the flexibility of running from main power or it can run on a 12 volt battery with a solar panel so no worries about running power out to the coop or dealing with power outages. The electronics are simple, intuitive yet very sophisticated.

The auto door system carry's a 1 year warranty ,what you will get in the installed package is shown below in the pictures this makes up the whole system an installed it is $265.  Ready to use with photo cell that opens the door at dawn an closes it at dusk. we can also do a programmed mood where you can set the open an close times.the 3 watt solar panel will keep the battery fully charged so no need to supply power to it,so you can place your coop any where you want,an not have to worry about going out to open your coop in the morning an shutting it up at night. Ncbackyardcoops is the only coop builder in NC SC an Va to offer this system with its coops

A Little About the designers of the Auto door system.

Established in 2007, we are the premier manufacturer of automatic chicken doors. Together we have over 50 years of electrical and mechanical engineering experience that gives you a better product. 

​​Mark and Tony started this business out of need.  The joke was that we paid $5 per egg when we both started out.  We were friends, both had ranches about 5 miles apart and both struggled to open and close the coop each day.  We lost hens left and right, often jumping out of bed remembering to close the coop.  Our wives just shook their heads at us.  Our first doors were THOROUGHLY tested at our homes!  And since then thousands and thousands of customers have joined us in not being slaves to our birds.  We thank each and every customer.  God Bless You!

Brass-aluminum.  A touch of lubricant twice a year. Plywood is unstable and will 'stick' open sooner or later.

Power isn't often available at the coop.  Power outages affect mains power timers and they stop working. Not true for a battery timer.

Many coops do not have the height available or the'standard' stud spacing to support most doors.

Mechanical timers have failure issues in dirty coop environments and require constant power.

When it gets extremely cold, our circuit compensates and drives the motor harder.  When warm, the motor gets less power to limit force.

Plastic pieces are easily lost.  It does not get easier than the Pullet-Shut programming

Switches are a high-failure rate problem in coop doors due to dust and humidity.  Switch failures equals door failures.

Pullet-Shut lets you define how wide you want the door to open.  And after the first day's programmed open and close times you can open or close the door anytime without changing the programmed open and close times.

Pullet-Shut limits the motor torque to avoid injuring chickens if stuck in the door.  Every evening the door opens again for 10 seconds after the programmed
close time to let in any 'late' chickens.
