Specifications

  • Control: Light sensor

  • Self Locking: No
  • Safety Mechanism: Yes
  • Power Source: Battery (6V x1)
  • Warranty: 1 year

The Ador Store ADOR1 Automatic Chicken Coop Door uses heavy-duty galvanized steel for durability. 

The ADOR1 relies on a 6-volt lantern battery to operate. It lasts up to one year, making it more convenient than AA batteries. 

An automatic sensor controls the opening and closing times based on the sun. So you don’t need to fuss with programming timers or worry about the changing of the seasons. 

You still have some flexibility with this sensor, though. You can set the door to open early-close late, open late-close early, or default to the standard sunrise sunset times. If you have early rising birds, you can let them out as soon as they wake up.

It also has some extra safety features. You can select the last call mode to open the door a second time to allow any dawdlers to late access the coop. It also has a mechanism that senses any obstructions (like a lazy hen hanging out in the door), stops, and then retries to close. 

While it isn’t self-locking, it uses a drive sprocket rather than a string to open and close the door. Since the sprocket is always engaged and there is a motor brake, a predator like a raccoon can’t raise the door and enter your coop. You can sleep easier knowing your flock is safe.

If you are looking for low maintenance and easy to install automatic door opener to keep your chickens safe, the ADOR1 is a solid choice. Its sensor automatically knows when to open and close your door, and the safety features keep your birds protected in the coop.

How to choose the best Automatic Chicken Coop Door

When looking at automatic chicken coop doors, the choices and features can seem overwhelming. But by asking yourself these a few simple questions, you can easily decide which door is best for your lifestyle and flock.

Controllability: Remote Control vs Light Operated vs Programmable Timer

How “automatic” do you want your door? 

When it comes to deciding which automatic chicken coop door is best for you, one of the first things to consider is how much control you want over opening and closing time. The three types of controllers are programmable by time, light operated, and remote control. 

a. Remote Control

The most basic option is a remote control. This allows you to manually open and close your door without needing to enter your coop. If your door is someplace inaccessible or you simply want the convenience of it opening at the touch of a button, this is the best option for you.

b. Light Operated

While those of us who keep chickens know that it is a myth rooster crow only at sunrise (they crow all day and night), according to Dr. Jacob from the University of Kentucky, chicken roost based on daylight cycles (2). 

“The “flying down” time in the morning is typically 30 minutes before dawn.”

If your flock doesn’t have any special needs, a light-operated door opener is for you. These controllers have light sensors that open the door when at sunrise and close it at sunset. So you don’t need to worry about figuring out a complicated control panel. Just set it up and turn it on.

c. Timer

If you want to have more control over what time your door opens and closes, a programmable timer-controlled door is for you.  With this feature, you can manually set the time when the door opens and closes. Some even come with a sensor as well. These allow the greatest amount of flexibility but can be the most complicated to set up. 

Safety Features 

The safety of your flock is always a primary concern. So this is a factor to consider when choosing the best automatic chicken coop door opener. There are a couple of options available to provide added protection from the dangers your birds may face.

a. Self-Locking Door

One of the reasons we keep chickens in a coop is to help protect them from predators attacking in the night (3)

“Keeping chickens indoors at night is easily the most important and effective way of protecting free-range birds because many predators are most active between dusk and dawn.”

If predators are a big concern for you, consider a model that has a self-locking door. This prevents predators from opening the door and invading your coop. 

b. Safety Mechanism

Another safety feature to consider is the safety mechanism to prevent the door from closing while a chicken is in the way. While most doors move slow, there is always the risk a chicken will decide to sleep in the doorway at sunset. This could potentially injure or even kill the unfortunate bird. 

Materials And Durability  

Most automatic chicken coop door openers are designed to function outside in the weather, but not all are created equally. If you live in an area with extreme heat or extreme cold, or lots of precipitation, you want to ensure that the opener will work in your environment.

You may want to consider the material it is made out of as well. Doors are usually either metal, plastic, or wood. While this is mostly an aesthetic choice, there are some practical considerations as well. Different materials hold up differently to moisture (4). 

Power Source: Battery vs AC vs Solar

How will you power your automatic door? 

There are several factors to consider when thinking about power sources for your chicken coop door opener. Weather, the accessibility of main power, and the ability to connect to solar power are all things to consider. The three ways to power your door opener are battery, AC power, and solar power.

a. Battery-Powered Automatic Chicken Coop Door

Many of the automatic door openers run on AA batteries because it’s easier to maintain, especially when there are regular power outages in your area or if your coop doesn’t have an electrical connection. It is also a great choice to follow one of our chicken tractor plans and move your coop often.

However, batteries are not without their problems. Extreme temperatures can degrade battery performance (5), and some customers complain that batteries wear out quickly. If you opt for a battery-operated door opener, look for one with a low battery indicator, so your door doesn’t unexpectedly stop working.

b. AC-Powered Automatic Chicken Coop Door

If your chicken coop has power, then AC power will be your most straightforward option. Simply plug the unit in, and you and your flock can enjoy the convenience of having an automatic chicken coop door. 

However, you should avoid the temptation to run an extension cord out to your coop because there is a high risk of shorting the power line. If you live in a place with frequent outages, you will want to make sure the door has a manual option and check that the program doesn’t need to be reset every time the power goes out.

c. Solar-Powered Automatic Chicken Coop Door

If you are off-grid or your coop is far from your power, a solar-powered door opener may be the way to go. Many of the automatic door openers can connect directly to a DC battery charged by solar panels. You will want to ensure that your solar will generate enough power to open the door as often the motors are power-hungry. 

Door Size And Ease Of Installation 

The last thing you want is for the door size to be too small for your birds. If you have large chickens, you want to make sure that they have enough space to pass into the coop.

It is also essential to make sure that the door will fit into the existing structure. For example, If you have a small A-frame chicken coop, perhaps a door that opens horizontally will work best. Doors that open vertically need more height. 

What if you don’t have a coop?  

When you start from scratch, you can ensure your automatic chicken coop door fits into the design you choose. There are plenty of great options out there. If you are good with tools, check out these do-it-yourself or pallet coop ideas. Don’t worry if you are short on space or not so handy.  Maybe one of the best chicken coop kits will work for you. 

Warranty Coverage 

The last factor you will need to consider is the warranty. This is a big investment in your chickens, and you want it to last. Making sure your product has a decent manufacturer’s warranty can help give you peace of mind. If anything ever goes wrong with your automatic chicken coop door opener, you can use the warranty for repair or return.
