Recommendation As the co-author of “Chickens for Dummies” and owner of www.BackYardChickens.com , 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.  If you are looking for an automatic door for your chickens, you definitely need to check out the Pullet-Shut door at www.chickendoors.com .
