Regarding the run area
@Cyprus - I love the cattle panel hoop houses. 4 of them and you've got a 16 x 8 run. You can cover with whatever you please but it makes for a solid foundation and I love that you can keep adding more if necessary. I went balls to the wall and used pressure treated 2 x 6's for a base frame and dug in hardware cloth. I use mine as a greenhouse but I have resident rabbits so I needed it secure. Nothing like having little fertilizer machines where you need them most!
Cattle panels are awesome - I use them for everything. Perfect for trellising kiwi too!
