chicken coop lasted almost 6 years, using Linda Woodrow’s design as described in the Permaculture Home Garden. It did it’s job very well and kept all the chooks safe from predators. But it went downhill the moment the kids started “helping” with collecting the eggs. They have to make it over the first two white rings to get inside. It started to sag, the chooks kept getting out, it got patched up numerous times, my seedlings too, until one of the banana trees crashed on top of it. The End.
This is the geodesic design. It still fits the existing circles of our mandala garden, but should be stronger. It also makes it easier to create a lower instep. We re-used the roost and the tarp.
