chicken coop motor












  • Includes motor, AC-DC Adapter, lift-string, wall bracket, and illustrated instructions.

  • Reversible motor works like a fishing reel.

  • Motor stops door at open and closed positions you set.  No counter-weight needed.

  • Motor can lift and lower a door up to 10 pounds, with door openings up to 25 inches.

  • Motor opens and closes door smoothly in a few seconds.  It never allows door to drop suddenly. 

  • If your door swings open, convert it to a "predator-proof" vertical lift door with side-channels. 

  • Plug-in ready to your lamp timer switch.  Also X-10 compatible.




  • You decide what time your chicken coop door opens and closes  thereafter its automatic!

  • Sleep a little later.  The D20 opens the door each morning allowing your hens to feed or free-range on their own.

  • If you arrive home late, or if the weather is so poor you cant attend your coop on-time, relax because chickens enter the coop about the same time every day, and the D20 will automatically close the door at the time you set.

  • You can also set multiple door openings and closings each day.  This can benefit in several ways.  It can influence egg production by exposing hens to longer periods of daylight by preventing them from re-entering the coop too soon.  It can foil small predators that sneak-in to steal eggs after your hens are out.  And, it can help manage heat inside the coop.            

  • Raccoons, fox, dogs, cats, coyotes, etc. eventually give up and go elsewhere. 




I can leave my chickens for the weekend and not worry.   Steve, Vermont


My chickens make a ruckus if I don't open the door on time, and then my neighbors complain.

        My problem is that I can't get up at that hour because of my work schedule.  I really appreciate the

        good sleep that I now get because of my new motor.   Cindy, California


My husband gave it to me as a gift.   I thought it was silly but now Id never give it up.   Robin, Texas


Nice product saves me time and I dont lose sleep wondering if I closed the door.   Jack, Missouri


I dont lose chickens and eggs to varmints like I used to.  Motor paid for itself in a few months.   Meg, Oregon


The battery feature is quite satisfactory given no electric power near our chicken house.   Edward, England

Note: Many of the above components were successfully used to operate D20 motors in remote areas.  We added a 12 volt solar charger and our battery remained fully charged.  Without solar charger, battery needed monthly charging; more often in winter and northern geographic locations.

Correct Timer: Never use a timer that has "Adjustable (low, med, hi) motor speed control".

Correct Battery:  12-volt, 8Ah or greater.

Correct Solar Charger:  12-volt to 18-volt, 1 Watt to 2 Watts.



door materials ... control switches ... automatic night light and security system


Doors   We recommend that you make your coop door from plexiglas, aluminum, marine plywood, or 2-side tempered masonite.  These materials offer trouble free operation.  Maximum: 10 pounds.


Controllers   We recommend AC lamp timer switches, X-10 control, or battery with 12-volt timer.

We do NOT recommend dusk-to-dawn controllers because on overcast or stormy days, especially in winter, they can prematurely close the door leaving your hens locked-out overnight and at risk of predation.



Automatic night light   FREE PLANS ... Build automatic night light and security system for your coop.

Here is how it works, and how it can help you:

  • When the D20 motor closes your coop door, an exterior light automatically switches ON.

  • The light can be seen from a great distance and provides visual confirmation that the door is closed.

  • Area around coop is lit so that you can see if predators are around.

  • Light automatically switches OFF when motor opens the door.

  • Works with or without motor.  Light turns ON and OFF if door is opened and closed manually.

A Universal Power Supply (UPS) can give you peace of mind.  Sometimes called a computer backup power supply,

these devices are inexpensive (as low a $50.00) and can keep your chicken coop door opening and closing on your

time schedule, even during a power interruption.  Here is how it works ...


First, plug the UPS into the AC electric outlet in your coop.  Next, plug your lamp timer switch into the UPS outlet, and

then plug the D20 motor into your timer.  Set the timer to operate the motor so it opens and closes your coop door at

the times you desire.


The UPS passes AC power through to your timer and keeps it running as normal.  But most importantly, it has an

internal battery, a DC to AC electric converter, and a sensor to detect whenever the AC electric power in your

coop goes OFF.  If that happens the sensor connects the battery through the converter and supplies AC power

to keep your timer running for 30 minutes up to several hours.  So, if AC power goes off when your coop door is

supposed to open or close, everything will still work as you scheduled.


UPS devices are readily available at Target, Best Buy, Wal-Mart, Staples and on-line.  Wal-Mart offers a 450VA UPS

Model BE450G for $52.99.  The higher the VA or Watt rating (600VA is more power than 450VA), the longer period of

time the UPS will keep things running.  Staples offer CyberPower Model CP625HG which has 625VA for $59.99.  Shop

around for best deal ... but do not buy used.  If the power in your area goes off for short periods of time, you

probably don't need a UPS.  However, if power goes off frequently for an hour or more, and is unpredictable, a UPS

can keep you and your chickens happy.
