    Basic Backyard Coop--Keep It Simple, Make It Fast

    My start in backyard chickens was completely by accident, but by gradual measures I discovered the joys of fresh eggs (yum!), the the instant composting abilities of chickens (food scraps to manure in less than 24 hours!), the tireless labor chickens provide in turning my soil (accepted form of payment--chicken feed!), and the endless fascination and charm of my little “fleurs du jardin.” I raise Belgium d’Uccles and d’Anvers with a few silkies on the side. I have a small flock, currently numbering about 25 on about 1/2 acre. When my flock first started expanding from the initial 6-ish d’Uccles, I started contemplating installing a “super-coop” with multiple interior and exterior enclosures, electricity and plumbing. Such an edifice was within our budget and building capability, but something held me back. A career shift had nudged me in the direction of working with local sustainable food folk and I began to advocate on the pleasure and utility of backyard poultry keeping. Helping people deal first-hand with the obstacles that can make starting a backyard flock intimidating changed the direction for my own backyard completely. What follows is my experimental coop design (still a work in progress) which is part of my larger simple and affordable backyard poultry-raising/keeping model.

    My first coop I designed and built completely on my own (it shows). Back then I was challenged in both the design and tool use areas. I took as my inspiration a friend who liked to design items that used only 1 sheet of plywood. I tried the same idea for my first coop--and was able to come up with a design that used 1 sheet of plywood plus a bit more (Coop layouts and pictures are below). There were problems with the design mostly having to do with my tool challenges so for the Mark II design, I recruited my fiancé who has the sometimes exasperating tendency to create for you the Taj Mahal when all you asked for was a lean-to (hence his non-involvement in creation of coop Mark I). His additions included an interior frame consisting of 2 x 2’s and slightly taller coop height. This was necessary because the roof is pitched and I discovered that you can’t dictate to roosters what direction they need to stand on their roosts in order to keep from bending their their tail feathers. The Mark III coop extended the walls a bit higher and was constructed of 3/4” plywood instead of the previously used 1/2” plywood. This coop is very solid and secure, but is on the upper limit of what I can move by myself, so I consider it not quite as successful as the Mark II since my goal is a small coop that can easily be moved by one person. At some point in the near future we will be constructing a fourth coop that will be a further refinement of what we liked from the second and third coops.

    What my coops are (in no particular order):
    • Designed to get a potential poultry owner up and running quickly.
    • A simple to modify or customize design.
    • A no-frills design (no windows, venting is incorporated into the lid design, simple nesting boxes without special “egg doors”, no insulation, feeders or waterers).
    • Small (designed for 3-4 large or 7-10 small chickens).
    • Economical (under 50.00 in purchased materials).
    • Quick to make if necessary (for unexpected chicken rescues or impulse buys).
    • Designed to be kept in a larger enclosure.
    • Mobile (no permanent foundation and light enough to be moved by one person).
    • Able to be built with simple tools and no advanced carpentry skills.
    • Consisting of a simple, clean design that won’t cause embarrassment if the neighbors see it (it is basically a well-made box).
    • Useful for small flock breeding projects.
    • For some poultry owners a “good enough for now” starting point until a more comprehensive coop can be built.
    • Easy to clean.
    • Dry and comfortable for chickens.
    • A safe place my chickens seem to enjoy gathering in at night

    What my coops are NOT:
    • Designed to be anything other than secure nighttime housing and comfortable safe nesting for your chickens.
    • Secure against large predators. A bear would probably be able to tear them open or push open the lid. But I do not have to deal with bears where I live. I rely on the sturdiness of the exterior run to provide the majority of my protection from the occasional wandering raccoon. So far the only casualties I’ve ever had are from hawks and a neighborhood Jack Russell terrier that dug into my yard. Attacks have only occurred during the day when the chickens were out.
    • Warm enough for bitterly cold winters. The coops have no heat or insulation, although I imagine insulation could be added easily enough. In the 3 years I have worked with this coop design, my winter lows have been down to upper teens and my chickens have had no problems. I am well aware (from having grown up in the Midwest) of what -40 temperatures with -70 wind chill feels like and am certain that in such a climate this coop design would need some degree of retrofitting to keep the residents comfortable.
    • Completely waterproof. The oversize pitched roof sheds most rain but by design I keep the coop in a larger enclosure that completely shelters it. Painting or sealing an unsheltered coop would go a long ways to protecting it, but the roof venting might still allow driving rain to get in. As an experiment I have not painted or waterproofed my coops because I am monitoring how well the design holds up with no intervention or protection. For Science!
    • A labor-saving device. There is no automatic feeder (but you could add one), automatic waterer (but you could add one), automatic door (but you could add one), wheels to facilitate moving (but you could--you know), or easy-access egg door (you have to reach inside the coop to gather eggs or change the design to add one).
    • The Taj Mahal.

    Design Evolution: The original “one+ sheet of plywood” design looked something like this:


    The lid was slightly longer and wider than the box it covered and was raised on attached wooden blocks to create venting at the ceiling. The entire bill for materials came to about $29.00. The coop was placed in a larger enclosure on 4 16” square concrete pavers. Very basic, very simple, but not an ideal structure. From that humble beginning, this layout was born:


    This design uses 2 sheets of plywood (with some leftover cuts) and 3 lengths of 2”x2”x8” internal framing as shown (the framing amount includes extra for roosting bars). The coop is assembled with wood screws (1 5/8" x 8 square drive exterior screws for most of the project) and the construction only requires measuring devices, screwdrivers, drill with driver and circular saw (however cuts could be done with a hand saw). I had the lumber yard do all the initial large cuts on the plywood sheets. The bill for materials came to $47.28, including all hardware.

    The following photos will fill in the blanks and provide more construction detail:

    Important note about ventilation: Since I didn't get a really detailed photo showing how the ventilation is incorporated into the lid design, I am including a diagram that will show how the lid functions. To wit:


    (Please note--this illustration is not to any particular scale!)
    The blocks on the underside of the lid offset it by about 2" and allow air flow continuously. In the warmer weather I pull the lid slightly forward and use the block on the front of the lid to further offset it. This raises the entire lid and allows maximum air flow. The chickens are comfortable in winter because an optimum level of heat is created and maintained by their warm little bodies, but the excess moisture is vented at the roof. Summertime comfort is maintained by the extra venting at the roof. The coop door stays open all day. The system is embarrassingly simple and it works! I have never found signs of excess moisture in the coops or observed my chickens being too hot or too cold in these coops. In the morning when I let them out I frequently see little faces looking out along the gap at the roof all eager for breakfast. I have a small scale breeding program and some of my birds are shown, so having healthy, happy, beautiful little partners in my garden is very important to me. However, I am also aware that I live in a somewhat mild climate (teens to 105-ish) and can easily see that changes to this design would be necessary in climates more extreme than in Oregon.

    A few extra notes, my coops are sized for bantams (door size 12" x 12" and extra 2 x 2's for the roost) obviously large breeds would need appropriate door and roost sizing. I still use just 4 concrete pavers for a foundation in order to keep the design 100% portable. For cleaning I just pull off the lid, remove roosts and nest boxes, drag the coop over to my composting area and dump it. What could be simpler?

    What I am looking forward to in the next iteration: I am looking to change my nest boxes, I like the Ware design. I think the next coop will be a mix of plywood thicknesses as I do not like the 3/4" plywood lid. It is too heavy for my liking and as mentioned previously it is difficult for me to move the coop by myself. I am considering adding a lid prop for when I need to get into the coop for extended periods. Also, I am working on a possible door redesign for larger breeds as the coop is currently 27" tall in the front and a sliding door can only be lifted so far. I don't like the amount of wasted plywood in this current design, even though I've never had a problem coming up with uses for the excess. Any better layout suggestions would be gratefully accepted. Other than that, I'm happy with how well this design is working out for my backyard and for others. Also, This coop is only the beginning of a conversation. See it as a point of departure--customize it and make it yours! Always looking forward to input and suggestions!

    Please understand, both design and construction here are intended to remove or reduce barriers to backyard poultry keeping. I know all the professional builders are laughing themselves silly reading this, but real concerns expressed by real people were factored into this plan. 100 years ago nearly everyone--rich or poor, country or city dwellers kept a garden, chickens and (usually) bees. It was ultimate food security and a hedge against hard times. I see great value in restoring that lost part of our heritage and the natural rhythms of our lives. I am doing my part to help others discover the joys and utility of Backyard Chickens.

    "Needs some Rethinking"
    3/5, 3 out of 5, reviewed Dec 6, 2018
    Feel this is a more expensive card board box, I embrace the idea just not the full design. Sure its easy and cheap, but really lacks in many departments. For one the ventilation idea seems like an after thought and seems poorly thought out. Ease of design and construction along with cost is awesome. In my humble opinion a roof should be a roof and chickens prefer side angles versus over the top predatory 'surprise'. Checking the nest box seems like a task, clean out...another task. Just leaves me with an over all 'Lets convert my dog house to a chicken box and call it affordable'.

    "Simple coop for bantams"
    4/5, 4 out of 5, reviewed Sep 14, 2018
    This is a well written and well illustrated article on the construction of a simple box type coop for some bantams. Pragmatism and utility drive the decisions, and on the whole deliver something that could be built by most people, with a few tools, and at little cost, so in terms of its own aims, this is a very successful project. That it is scaled for bantams might be more prominent, rather than an afterthought, but those wishing to build for large fowl could easily follow the steps here and use this for inspiration and guidance.

    is there any way this is for sale and what would it cost without the nesting box if its not for sale then i wont lose sleep dont worry i just an curious
  2. gillyfleur
    Thanks for the comment! My original intent was to use this coop for breeding groups and quickly realized the potential this design had for folks getting started in keeping backyard chickens. My little bantams will also cram too many of themselves in the coops and when I close the coops in the evening I shuffle them around so there are no more than 10 per coop (the maximum for my birds).
  3. Tuhmu
    Thank you for this, this is exactly what I was looking for. Something simple and basic, for using as a breeding pen for the spring/summer. Thank you thank you!

    Some other ideas for you - and your readers: first, however, you should know that I share most avidly your views, mission, goals, and objectives. Chickens are so very much a part of our human heritage that every person should be able to keep them, successfully and comfortably, no matter what his location or finances provide. I appreciate how you've helped to make this possible.

    Re: the coop: is there some reason it slopes from back to front? Wouldn't a higher front permit a taller pop door?

    I have mixed old exterior wood glue with old wood patching (elmer's) compound to make a sort of seal for cut plywood edges. It does a good job of weatherproofing these vulnerable areas, and I can recommend this treatment as a way of using up old glue and wood patch. Especially if the edges are not protected or under cover.

    Why didn't you choose a pop door that is hinged on the bottom and swings down to open and latches (barrel bolt) at the top when closed. Unused polyurethane floor panels make great door material, btw, and often you can get them free.

    It looks to me as though your coop could benefit from some cross bracing - or something to strengthen the joints - since it will be moved and turned to dump from time to time and will receive a bit of wear. How has it worked out for you so far? Could a 60-70 y.o. lady manage the maintenance on this? What about hinged double doors in the front that could be opened as an access for cleaning? Or is this getting out of the range of simple?

    I am interested in what you've come up with after living with the coop for awhile.

    Thanks again.

    I love this little coop. It is a perfect size for my small breeding groups - and a great use for the dozens of used plywood sheets my friend gives me. I would put a nesting box accessible from the outside, and mount both feeders and waterers externally, as well, feeding them through the wall, with PVC pipe and horizontal nipples, so that the chooks could access them from the inside, and you could access and fill them from the outside. This arrangement could be a real boon in foul weather. I have used large deck boxes about the size of this coop. They make good brooders as well as huddle boxes for larger groups. I like the lid arrangement, but it would probably need to be secured some way in high winds like we have here. I have found that it is difficult to achieve adquate ventilation in windy wet or snowy cold weather. Nowadays I locate my small breeder boxes within a larger tarp covered hoop coop made only with rebar, PVC pipe, tarp, and a plywood end on the wind side. They are about 7'w x 12'L x 6'H, and they give my birds some dry area to walk around in when the weather is foul; the protection they afford also lets me keep the lids propped open in nasty weather, for ventilation. Your coop plans are exactly what I've been looking for. My birds, btw, are are large Large Fowl and they really do like to cram themselves into the deck boxes at night, sometimes as many as a dozen. (They don't HAVE to, though)

    Thank you so much for creating and posting your article.

    My bad. I looked over this coop page again and found the answer. Thank you for sharing!
  7. Copper Creek
    Love this coop. I was wondering, how many chickens do you have in each one?
  8. mpgo4th
    Hello, I keep a flock of 12 laying hens and rooster. My wife wants a few silkies as pets but they would be picked on in my coop and pen. I wanted to thank you for posting this design as it is perfect for my needs. the only change I made was to use 2x4 treated legs to raise mine off the ground 2 feet. With buying screws this coop cost me $58 to build. Thats a lot cheaper than my $900 coop. No its not the nicest or prettiest coop out but if you want a few bantam birds as pets of breeders, this design just plain works!
  9. lightchick
    Ok so how many chickens can fit in it????
  10. gillyfleur
    In 2009 dollars, this cost me $47.28.
  11. lightchick
    How much did it cost? Could I keep 6 chickens in it? Great coop!
  12. SpeckledDottie
    Just wanted to add that the coop is working great. I used the 4'10" piece labeled "excess" as the roof. I attached 2 hinges to the roof for easy opening. I attached a latch to the underside of the roof and the side of the coop and have a key lock. I use a piece of wood to prop the roof open. I added tin to cover the roof. It's easy to clean out with the removable roosts. They are spaced far enough apart that the water and feeding containers can be easily lifted in and out. There's enough room to have a warming lamp inside. I have mine sitting on a platform 6 inches off the ground. I take the door off and use it for the ramp. I attached a 4'x8' run to it. I feel confident I could easily resale this coop to another beginner for the cost of supplies.
  13. Pozees
    Love it! You could always have the door slide side to side, or just a "pop" door with a hinge at the top and a hook and eye with a chain to hold it open during the day.
  14. DonGallina
    I like the simplicity of your coop design. I'm using it as the basis for my coop. One question though, according to your plywood cutting plans the lid should be 4' wide, but in the picture it is a few inches larger on each side. Am I reading the graphic wrong?
  15. brooklynchicks
    what kind of kennel is your coop in?
  16. Raech
    Would the size you have be ok for Dorkings? I only get three until we buy actual acres. Love the price tag that comes with it. It would also be a good design for an older child to help build instead of the typical bird feeder. Definitely will have my son help me with this.
  17. FloridaRedneck
    This is an excellent design, I started my build today!
  18. coffeekittie
    This is EXACTLY the kind of coop I was thinking to build, but I had no real idea of a design. I have d'Uccles and other bantam breeds that need new, bigger pens and better coops. Thank you!
  19. AdirondackChick
    Great information! I think anyone would be able to follow your plans! Wonderful little coop for just a few birds! They look very happy! Great job!
  20. gillyfleur
    Thanks for the comments, I realized that I hadn't included any illustration on how the venting at the roof works. I have now edited the article to offer further explanation and a diagram. I'm looking through my photos to see if I can add one for further illustration. Keep the comments coming, they serve to improve my article!
  21. Bogtown Chick
    I definitely recommend you put ventilation and light for happy chooks.
  22. The Old Yolks
    Its nice, but I would strongly recommend you, at the very least, drill some holes around the top.
  23. Bulldogma
    Neat and simple, but from the pictures I can't see the ventilation. What do the vents measure?
  24. paridisefarm2009
    I think it is Great are you planning on Pitting in any vents or opening For air To flow?
