Earthbag Building & Other Natural Building Methods

Bill Mollison’s Greenhouse/Chicken Coop

I found a very good greenhouse design by Bill Mollison (co-developer of Permaculture) in this video called Intro to Permaculture 12 – The Industrial Egg vs The Permaculture Egg. This video is a part of Midwest Permaculture’s Free Internet Webinar Series. It is one of eighteen segments from the first webinar of the Foundations of Permaculture Webinar Series. (Skip ahead to 1:12 if you know the background of industrial chicken farming and want to go right to the greenhouse info.)

Is anyone interested in building something like this with earthbags? Do you want to help design an open source plan? Ideally, a few of us can work together on the design and then build one. The design part is easy. We mostly need someone who has the time and money to build a greenhouse/chicken coop fairly soon. Leave a comment below if you’re interested in working on this project.

    This sounds like a great idea i want to try this on a large scale and i’m about to buy some land in colorado kind of pricey for where its at buy i’m isolated from everyone. It’s going to be cold so i want this for the winter month’s. I will have 5 acres and want to put this smack dab in the middle and use it during the winter and after winter turn it into a full green house and have the chickens roaming free in certain areas to cut down the grass, but would the chickens still need to have food during the winter? Wont it cost so much for feed?

    • Owen Geiger says:

      Yes, the colder the climate the more you’ll have to feed them. Just like humans, it takes energy (more food) to stay warm. But being inside the greenhouse/coop during the winter would reduce how much food they need. Look into growing your own feed if possible.

      • paul says:

        Whats the best feed to grow? I’m going to be in the Rockies so I need something to grow before winter. I will have a green house for my crops that I need year around, do you think that the chicken smell will carry over to the Plants? Thank you for your reply

    Which of Bill Mollison’s books discusses greenhouse/chicken coop construction?

    • Owen Geiger says:

      If you don’t get a reply, go to a big bookstore in a big city if possible and preview the books before buying.

    We are looking for plans to build our chicken coop greenhouse combination in Lake Arrowhead, CA.

    can you point us in the right direction

    I am completing my greenhouse chicken coop/run this week. Fifty chicks are on their way. 10 ft is enclosed as their coop and there is 30 foot for run area. I will be planting grass or clover for them to peck and mixing in a at least 5 yards of cow manure with worms and insects. if interested pics will be @

    • Carl says:

      What kind of clover are you using?
      I’m considering crimson/red clover as a perennial out in my orchard and have chickens/ducks go after.

    We are very interested in building this concept. We live in Montana and are interested in a year-round greenhouse idea and have been wanting to build a chicken coop as well. Very interested in the recycle, earth, natural building concept.

    • Owen Geiger says:

      Please take photos and let us know how it goes — construction process, costs, performance in your climate. Every little bit of information makes it easier for others to do in the future.

    We’ve been looking at this picture for ideas for our coop. I toyed with the idea of using earthbags for our chicken coop, but don’t have any experience with it. We plan on starting to build our coop this spring and would love to be a part of this. What exactly do you think would be required on our end, for budgeting purposes with time and money? We live in the state of Michigan.

    • Owen Geiger says:

      In cold climates I would use gravel bags for the foundation and straw bales on top. The roof could be recycled board or wood poles covered with metal roofing. Check prices in your area and see what it would cost. No experience required. This is very, very simple. Just plan ahead a bit and you’ll be fine. Make sure the chicken pen or chicken run fencing is buried so animals can’t dig underneath.

  7. Carolyn Sue says:

    I am very interested in building a greenhouse with a chicken coop. I live in Santa Fe, NM. Will keep you posted on design and project in general. Any feedback will be greatly appreciated.
    So glad to find your info!

  8. Dave says:

    A very good post. I find with building a chicken coop, the first thing you must do as you build a chicken house is take the time to plan the entire coop before you build. Many people make the mistake of building too early and then find out they have built too small because of all the additional pieces that have to go inside.

  9. Green James says:

    Thanks for posting this. Really great information on greenhouse gardening.

    Excellent concept, I’d like to try this on my small farm. I think my use of the building would vary seasonally. In summer I like my chickens outside on pasture in mobile coops so it might see alternate use. I think the coop/greenhouse combination would be a great season extender for starting plants early in spring and continuing to grow leafy greens for the household late into fall.

    I agree that ventilation is crucial and would influence what temps could be maintained in mid-winter. I suspect that in my very cold climate there would be a seasonal point where greenhouse production would stop for temperature and light reasons. I think it would still be a very useful passive solar coop for overwintering birds, even if it dropped well below freezing for periods of time…many heritage variety chickens would do just fine.

  11. Kelly Hart says:

    I’ve just been reading a very extensive and detailed book about raising chickens and what their housing needs are. Most of what is presented in the video is true, but there is one aspect of the concept that I question: adequate ventilation for the chickens. The author of this book, Harvey Ussery, has been raising chickens for over a quarter century, and the one thing he emphasizes above all else with respect to coop design is the need for lots of fresh air. He leaves doors and windows wide open much of the time, and there is a permanent ridge vent at the top. Even in climates with freezing weather he recommends this, for the health of the chickens.

    • Caleb says:

      I don’t think ventilation would be too much of an issue as long as a small exit is provided so the chickens can enter and exit whenever they like. An attached outdoor aviary wouldn’t require more than a few posts and chicken wire. Chickens like to be out and about during the day, but they roost at night and a greenhouse would be perfect–warm and sheltered.
