This is the third year my garden has been destroyed by birds. So I decided to use my garden as a run and then in the spring to plant in the same place. But I need to cover garden to keep chickens in, hawks out. garden is 12 x45. I put in a row of 4x4 posts and a ridge board all the way down , then just hung bird netting across the top and secured to the fence boards. then fixed an entrance for the coop and for pedestrian door. htis is not a secure run , so girls are not allowed to stay out at night. My dogs patrol yard day and night. the garden already had a chain link fence around it and chicken wire to keep rabbits out.
