How to cover a large run?

[Scooter&Suzie]

I have a big run made out of deer netting in our woods. I'm not sure how to cover it... It is 100' of deer netting in a circle. A hawk got one of my hens when they were out in it. Does anyone have any ideas? The fence is connected to some poles and trees, along with trees in the middle of the run. Those hawks make life so difficult...

hi I am probably off the mark here due to size but I use fruit tree netting and thread metal wire through the edges and to support it. It also stops the hens flying out.
