Kristen:
Your question was about poultry netting, but I'll share what I use instead. A simple 4 wire system. And it serves double duty to keep predators out and chickens in. I have also started using it for crowd control to keep birds out of designated garden areas. If grazed down to nothing, it may not keep them in an area like that, but most poultry netting might.
This is the system:

A fence of this type costs a fraction of what netting does, so enables you to enclose a large area measured in acres vs. square feet. When I first set it up, it was only two wires and that is what the birds trained on. To cross over it, they would walk on it, stepping on the wire to go over it. All of them did that and all of them eventually found themselves with one foot on the wire and one on the ground and got zapped on the bottom of their foot......and would launch about 5 feet in the air. After that, they respect the fence and won't cross it. So much so that the fence I am now using for crowd control is this one:

That is just a single strand of poly tape. Before that went up, the birds were going in there and scratching and digging and eating the young cabbage plants. Once it went up, they have only been in there once that I know of and that was a day when the fence was off. Since then that has grown to the point where it is shorting out the fence, which is now off. They walk past it daily, yet still do not cross that single white tape, even though it is not hot. If I took it down, they would be in there the same day.
So that 4 wire fence keeps the birds in (none have gone past it in over a year) and it also keeps predators out. Friends who live a few hundred yards away have a fox in their yard......saw it two days ago. We also have coons, coyotes, stray dogs, etc. and despite all that, none come into the chicken yard. I have never seen one and have not lost a bird of this flock to predators......that going on 18 months. One neighbor's dog made a beeline for the birds early on, hit the wire, yelped, went home and has not been back since. Their garden is no more than 100 feet from where the birds hang out and I've seen that dog lay down that close and it won't even look up at them.
Only downside of this fence is the ground beneath it has to be kept clear to keep it from shorting out. But that is the same with poultry netting. You scalp the ground beneath it with a mower and do that every time you move it and it will be fine.
But I also have two sections of poultry netting and am no longer using them as such. I prefer this system for ease of maintenance. I have found it works as well and is easier to keep going.
Others mileage may vary.
