New to the forums, I don't know where to put this link: so, here it is... here...
This guy builds these systems, but also has videos on how to build them.
They are set up in a "mandala" design of six sections, all fenced
to rotate in six months growing periods... chickens doing his cleanup
when each section's "season" is finished.
I liked the design because it provided enough food for his family,
protected his garden from deer and other wild animals.
It provided housing and food for his chickens close to the garden.
It was just so cool.
