We’ve started work on a Chook Dome. This is a classic “chicken tractor”, where the poultry will clear an area of seeds, and leave plenty of manure.
We chose 1.25” poly pipe. This was probably overkill, but worked out neatly as two domes from one 150m roll.
The dome design was from http://members.iinet.net.au/~helcreek. We scaled the measurements to make a 4.8m diameter dome, which suited our garden best.
We could alternatively have used the dome design in Linda Woodrow‘s book The Permaculture Home Garden, but preferred the geodesic nature of this design. Linda is the permaculture authority on chook domes, and her book is well worth reading even if you don’t use her (4m) dome design.
As the pipe was so heavy, it was a little hard to manhandle. It cut easily with an electric jigsaw. We drilled holes at the nominated places, ready to be joined with cable ties.
