I’ve gotten very behind. So sorry you had the hawk attack, I read it fearing the worst.I would welcome feedback on my current thinking about anti-hawk netting. I will put it all in a spoiler because it will be a bit of a long post.
First off, I am not trying to cover the whole of the chicken yard (defined by the electric fence). That is too big a project. But there is one area which is very popular with the Princesses - it is where they hang out to gossip and preen.
They like to sit on top of what I call the 'Open Runs'. They are not really open - but they have a hardware cloth roof rather than a solid roof. When I let the Princesses out they like to sit on top of the hardware cloth roof to chat.
In the summer this area is pretty well protected against both types of hawk because there is a tree (evergreen) and very thick lower level bushes and shrubs. Both sets of leaves hide the chickens well from hawks circling overhead, and from hawks sitting in the tree. I think the heavy foliage cover is probably why they like that area so much.
In winter the lower level protection is much thinner because the leaves fall. I think they are still quite protected from the hawk in the air, but a hawk in the tree has a clear line of site to where they hang out. It was a hawk in the tree that plummeted to earth to try and get Pooh.
I have tried to show the rough set-up in the sketch below. Pooh (in green) is sitting in their favorite preening spot.

My idea is to use the kind of brackets that hold flag poles onto the side of houses. I have one - they are cast aluminum and are designed (obviously!) to hold a long pole in place. Some are adjustable, and some are fixed with the pole either horizontal or at 45 degrees.
Instead of a flag, I would attach netting which would drape between two flagpoles to cover the area where they hang out - and drop down over the end of the flag poles but not all the way down to the ground so the Princesses can still jump up to their favorite spot.
In the picture below the purple/blue is to show the flag poles and the netting.
One benefit of the flag pole solution is that it will be easy for me to remove the flag poles to take down the netting in heavy snow or if leaves build up.

Let me know what you all think. All ideas welcome!
Hawk netting tax: Everyone has gone inside because it is snowing and very windy. Here is Pooh enjoying the snacks provided indoors.

I think that some netting will help, but that it should extend to the tree and bushes and if you can extend it to the ground on the other side of the bushes (hug the tree at height and then go down I suppose), that would be best, so that they have some place to run / fly to and to put something like twigs and branches between them and the hawk during an attack from inside the netting. Optimally they would have some height available with the netting, so they can do a vertical jump-fly avoidance maneuver in any direction. If it just hangs down in front with a slot, there’s nowhere to go and I can see them getting entangled and caught against it, and the hawk will use that.
If you’re out there with them when you deploy this then you’re helping to buy some time. But because the ends by the poles are not enclosed it’s not really a deterrent as much as an options limiter (that’s something though) for a Coopers Hawk, or even a Red Tail (the Red Tail here just dropped down onto Butters beside where the netting canopy ended). So if you’re there and watchful that will be good. To the hawks it’s a tunnel to easily figure out and fly around / into / through. Coopers Hawks are pros at woodland hunting, they understand the woodland understory and flying under and between branches. Pooh was at the edge of the open run in the picture, she will be vulnerable there. So give them room to escape to, thus the extended front edge over the bushes.
But I am wholly in the paranoid camp, as you know. If you can create a netted area that is really totally enclosed, even just a temporary spot you can feel assured they’re protected in, so you can nap and relax out there with them, I’d fully endorse that!
