We’ve had great interest in the beautifully constructed chicken domes that we use in the veggie patch. Anthony built the domes out of 3/4″ electrical conduit going off the instructions at www.milkwood.net/2009/07/27/how_to_build_a_geodesic_chook_dome/. Anthony adjusted the measurements to suit our 4m diameter circles. If you have any questions just comment below, Anthony is happy to help.
