What to Know Before Purchasing

There are a few important things to know, or think about, before you buy your hen house door opener, or you may end up with something that is not helpful to you or your hens.

As they can be expensive, you really need to shop carefully for the door that best suits your needs; this is where this guide comes in!

As an example

There are manufacturers that sell just the control box (i.e. door opener) and the door is sold separately or there are ‘all in one’ combination units with the control box and door. Read the advertisement carefully, you need an ‘all in one’ unit unless you are prepared to either pay a lot more or make your own door.

If it seems much cheaper than other models – ask yourself why? Most all in one (i.e. combination) models are priced between $200-400.

Desirable Features:

  • Ease of operation (e.g. fail safe and manual override).
  • Wide range of operating temperatures – down to below zero is optimal.
  • Slow, gentle closure (i.e. not a gravity-based closing mechanism) with a 30 second cycle time.
  • Waterproof control unit.
  • Wire is safely secured from rodents (and chickens).
  • Adjustable timer or light sensitivity for control box.
  • Warranty and customer service.

There are four main purchasing decisions you need to consider:

  1. Power Source for your Control Box
  2. Type of Control Box
  3. Opening Mechanism
  4. Door Weight

Each chapter below will explore these components and share our experience on types and designs you will require.

Power Sources for Automatic Chicken Doors

Chicken Coop DoorThe control boxes on coop door units can be powered by four different sources:

  1. Mains electric
  2. Batteries
  3. Solar
  4. A combination of all three

Battery Power is the way to go!

Most of us don’t have power supplies near our coops, so because of this most control boxes are battery powered.

Battery power is a constant and reliable source where you don’t have to check anything much except the control box to ensure it is functioning. Batteries also prevent against power outages and most good control boxes have low battery indicators so you know when to replace them.

The only drawback here is battery life.

You should expect to get 6-9 months from 4 AA batteries. Whilst this is relatively short-lived, it’s more than offset by the advantages of having an automated coop door.

Solar power is a great option for those of you who are off-grid.

It’s also great if you have your chickens in pasture and it’s far away from the house or electric source.

However, solar power can be a ‘spotty performer’ in areas that don’t have several days of sunshine, or in the Northern Hemisphere winter months.

Programmable Control Boxes (Light Sensors Vs Time Based)

Sliding Chicken DoorThere are two widely used modes for door operation:

  1. Light Sensor (Sometimes with time-based failsafe options).
  2. Timer Based (i.e. Clock).

Light Sensor

Light sensor operated doors open with sun rise and close at dusk or dark.

Since they are light sensitive, be sure that no light will trigger the door to open at night. Think very bright moonlight or a motion detector light, even passing car headlights – nothing like letting the fox into the henhouse!

We all know predators are smart, they watch for patterns and weaknesses. Once Mr. Fox knows that your girls are up at 6am sharp and you are nowhere to be seen, he may be bold enough to strike.

You will have to place the sensor carefully on a west facing wall to catch the morning sun. Some deft placements can delay the opening of the door if you don’t want them out at sunrise.

Timer Based

The second option is a timer-based solution. Some light sensor mechanisms are fitted with an emergency failsafe option which is triggered by a timer-based mechanism.

So, if the coop door hasn’t been opened by 8AM then open the door.

A timer-based option, without a light sensor, is our favorite solution as it is cheaper and programmable.

One big advantage of using the program or override feature is that you can vary the opening time based on season, day or need.

You will have to periodically adjust the program timing as the days get longer or shorter.

Our Pick: Control Box

  • Integrated timer and light sensor so you can decide upon which program to use.
  • Manual door release and failsafe mode to prevent injury to your hens.
  • 2.5lbs door lifting capability and easy to see low battery indicator.

Opening Mechanism

The opening and closing of the coop door has different power sources, programmable controls and mechanisms.

The mechanism can be either a:

  • Motorized Lift and Gravity Close
  • Motorized Lift and Close

Always select a motorized lift and close for a well-controlled open and close of the coop door.

The motorized lift and close should have an electric eye or positive stop to prevent against harm or injury to your hens.

Ideally, it should also have a small lip in front of the positive stop to prevent predators from sliding open the coop door.

What Size Door Do You Need?

This refers to the size of the ‘pop’ door.

Some units come in one standard size (12” x 15”); this is ideal for most breeds. Larger birds may not be able to squeeze through smaller holes!

If this is the case, an option is to use an aluminum door. An aluminum door will reduce the load on the motor as it can reduce the weight of the door by up to 90%.

A typical coop door can weigh 4KG, however, an aluminum counterpart, measuring the same size, will be 0.3KG. Typically, cheaper automatic openers will raise and lower doors of up to 1KG in weight. Better, more robust motors will raise a 4KG coop door and not strain themselves.

Not straining the motor is important for a smooth operation of the door.

A few models have variable sizes for the pop door entrance, so be sure what size door you require before you buy.

Common Problems with Automatic Coop Doors

Whilst researching automatic coop doors, and having used them for several years, you will find common problem areas with specific units or brands:

  • Avoid gravity lowered doors and always purchase a motorized raise and lower door. Gravity lowered doors can cause harm and stress to your hens if they get trapped.
  • Avoid cheap, poorly manufactured automatic coop doors, this can result in electric issues and potentially your coop remaining open to predators if the door fails.
  • If you live in areas where the temperature can regularly drop below freezing, it’s best to avoid using these mechanisms as they can simply freeze and refuse to run.

Automatic Chicken Coop Doors 101 Summary Table

Feature Options Our Recommendation
Power Source •Mains
•Battery (Typically 4 x AAs)
We recommend battery power to prevent against power outages and solar failures. Battery power should last between 6-9 months and should have a low battery indicator.
Programmable Control Box •Timer Based (i.e. Clock)
•Light Sensor Based
•Manual Override
A timer-based mechanism for opening and closing the coop door which can be adjusted based on daylight and days is the best option. Light sensors, even if they are adjustable, can fail too often due to cloudy days, shade and changes in the atmosphere.
Opening Mechanism •Motorized lift and close
•Motorized lift and gravity close
Select a motorized lift and close unit; ideally with an electric eye to prevent lowering jams or your hens being trapped in the door. Ideally, include a positive stop with a small lip to prevent against predator intrusion.
Door Weight •1KG
Typically, cheaper units will lift doors of up to 1KG in weight. Better, more robust units, will easily raise a 4KG coop door. You can always use an aluminum door to reduce the load on the motor.
Installation Type •Control Box
•Combination Unit (Control Box and Door)
It’s advisable to purchase the combination unit to prevent against poor installation and an over-worked motor due to an excessively heavy door.

    I got the deluxe model. It’s great. The door opens at sunrise,but can also be set for a time you want. It can close at sunset but I have mine close at 830 pm.But I did have to change my pop door because of weight. My girls like to be out late so once in a while they get stuck after curfew. I still check on them every night. My girls are trouble too , they are trying to dig out under the base of their run. I would definitely recommend getting one. But remember this is a great Help not a replacement for being a good chicken owner

    • Luc says

      There must be a way to install an old DC electric car window on its side powered by a 12 v car battery charged with a solar panel. Can all be purchased at a wrecking yard for very cheap. I haven’t figured out the timer mechanism yet.

  2. Garett says

    How about a top-hinged door? I have one in front of the nest boxes to stop the dear ladies sleeping in there. The door opens at daylight and closes at twilight. The door is lift to open and gravity close, so if a chicken gets trapped inside it can push the door open easily ( as has happened during a test run). Outside the square?

    • Adam says

      just run the string for the sliding door through two small pulleys and then attach it to an eye bolt at the bottom of your hinged door. It should then swing upward when the motor “lifts” the door

  3. Mark Lercher says

    I have not had happy success with an automatic door operner that closes downward (verticle). I highly recommend installing an automatic door that closes horizontal like a normal door. Here is the reason why. I have lost chickens (crushed) because they decided to perch right below the door and by the time the door reaches their back, the chicken is already at their lowest setting and can not move. A horizontal closing door will just push them out of the way, If you already have a verticle closing door, just turn it 90 degrees and you should be able to make it slide sideways instead of up and down.

    • Summer says

      Thank you
      We lost a young chicken this morning and I’m afraid she may have been trapped by the downward closing door 😞 Tonight we sat and watched as the hens like to roost right where the door is. We are devastated and have unplugged the automatic door. On Amazon we did not see any negative feedback. The hens are up in a roost house that is also completely fenced.

    Based on my personal experience of an automatic pop door, you’ll learn what you need to look for if you intend to buy one: the features which will help keep your chickens safe and the pros and cons of different power sources.

  5. Robert says

    Hi. This was a great list of preferable traits for a door. I was hoping that you could provide me with the name of the company that sells this perfect door you describe.

  6. Bill Campbell says

    My coop door is in the floor of the coop. Every auto opener seems to be for vertical. My opening is horizontal in the floor of the coop. Is there anything available that will work for me ?

    • Taylor says

      Couldn’t you just use a vertical door With the gillateen style door and lay it into the floor so the door opens from left to right and chickens jump done through ?

    • Amy Treneff says

      I just got the omlet horizontal closing door since mine is a hole in the coop floor too. Installed it today and it seems like it will work like a dream!
