Essential Info

The Add-A-Motor D20 Chicken Coop Motor allows your chicken coop door to open and close on a time schedule that you can set using any standard lamp timer or INSTEON controller. Simply plug the Chicken Coop Motor into your controller switch and it protects your hens and eggs, and saves you valuable time every day. If you arrive home late, or if the weather is so poor that you can not attend your coop on-time, relax, because chickens will enter the coop about the same time every day, and the D20 automatically closes the door at the time you set on your timer. You can also set multiple door openings and closings each day. This can benefit you in several ways. It enhances 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 such as mice and snakes that sneak in to steal eggs after your hens are out. And, it can manage heat inside the coop. Raccoons, foxes, dogs, cats, coyotes, and other egg-stealing and chicken eating wildlife eventually give up and go elsewhere.

    Was just what I wanted. Works great and was easy to install.I am plannig on purchasing another one.
    NATHAN -- free union, VA   6/5/2014
    It works like a dream. Or rather, while I am dreaming! We love it!
    ANDREW -- taunton, MA   5/30/2014
    This thing works wonderfully. Hook it up with a $6 timer and the door operation is automatic. We love it!

    Rob Parker -- owasso, Oklahoma   4/20/2014
    The motor is made completely of plastic parts, so longevity is a real issue. The first motor I purchased lasted less than 7 months, the second lasted perhaps a week. Gears should be made of something besides cheap plastic,
    DENNIS -- caucasian/white, NON, FL   4/19/2014
    Love it. I don't have to be there to let the chickens in or out. Had a few trial runs of the door shutting and the chicken still out. They let me know though. Don't know why I didn't get it before. Don't use it on a wood door because it can swell in the rain.
    CHRIS -- nampa, ID   3/29/2014
    The installation is easy. I had a bit of trouble trying to get just the right length of line, but after that everything works great. I have this running my chicken coop door and love it!
    ROSS -- seattle, WA   2/26/2014
    Great item! Works perfect. Install was simple
    JOSEPH -- grifton, NC   2/10/2014
    Good deal on this D20 coop motor. Built my own sliding door and installed in my coop, chickens don't wait for me in the mornings anymore. Saved money!!
    MICAE -- la jolla, CA   2/3/2014
    easy to install and works like a champ. I used a simple $5 analog lamp timer. with it my coop opens every morning and closes every night, all by itself.
    KEN -- wilsey, KS   1/23/2014
    Works great on my chicken house door. Very pleased.
    KEVIN -- bemidji, MN   1/9/2014
    Excellent price, fast and affordable shipping. I will definitely buy from them again!
    KARL -- oregon city, OR   12/26/2013
    The Add-A-Motor was easy to set up and has worked flawlessly. Very easy to follow directions are included. After installation I plugged it into a timer. The intent was so I didn't have to go out to the coop every morning and every night to open and close the coop sliding door. My problem has been solved with this motor and separate timer. Smarthome had a very good price, when I purchased this motor and the shipping was fast and efficient.
    DENNIS -- calistoga, CA   12/19/2013
    works great
    TOMMY -- fitzgerald, GA   12/19/2013
    Works Just as advertised.
    JOHN -- cottonwood heights, UT   12/5/2013
    This purchase was made because the previous purchase from Smarthome for the very same product 5 years ago died! So I ordered a new motor. Well I had kept all the original motor packaging and box from the first purchase and noticed that the new motor came supplied with a small insulator to keep water and moisture from running down the 12v power wire and into the motor assembly. This is a simple motor and mechinism that really works great for exactly what it is described as. I wish I did'nt have to replace the motor for this issue that they must have had complaints about because of the new "now included" retrofit fix!!!
    HawtDogFlvrWtr -- spotsylvania, VA   12/2/2013
    Got mine on 11/29/2013 and it works perfectly. I set mine up in an odd fashion and it works perfectly. The cord they provide might as well be red thread.. i ended up using weed eater line as it gives a bit but is strong enough to hold. This thing is strong and can pull up my 2 pound heavy wooden door without flinching.
    NELLEKE -- cambridge, ON   11/24/2013
    Works very well!!!! Easy to mount. Much easier than trying to build your own. Delivery very quick.
    SUSAN -- potosi, MO   11/18/2013
    This device was very easy to install and works great. Now I don't have to get out in freezing weather to let the chickens out. I would recommend a good timer with a battery backup if you loose power often.
    CARLA -- arvada, CO   10/31/2013
    This motor is working perfectly to keep my chickens safe. The first motor I received was broken, but was replaced quickly and is now working great.
