My run is a combination of chicken wire for the upper part, hardware cloth for the lower 3 ft (and buried another foot underground). The run is covered with poultry netting.
As far as planning for predators, I know a lot of people spend a lot of time trapping, relocating and killing wild animals. I think this is a complete waste of time, as soon as you kill one another one moves in. and I can promise that if your housing is inadequate, eventually you will lose birds to predators.
Predators kill because they need to to survive, it's not personal to them.
I also think that predators serve a purpose in our environment, and killing them leads to population growth of what we consider varmints.
Spending your time and efforts on building predator-proof housing gives you security that your birds will be safe whether you are there to protect them or not. You will have to zoom in on this picture a little bit (look over to the right) but I had a visitor a few weeks ago. I sat in the house and watched him without fear, because I knew my birds were safe.
