I have netting and trees and big pens. I put the netting up in sections around the trees. It isn't pretty but functions well. I do also have several coops. There were no trees initially I planted them all. Our land is mostly open pasture. I don't know if these pictures will give you any ideas. The netting is attached to the front of the coops. My fences are 5' tall. Good luck and have fun ...
This is a section of the netting I used.
