I know it is not much help for you now, AB, but I have always contended that chicken wire is for chicken, and not predators. I'm sorry for your loss, but even welded wire won't hold for a large enough predator. I guess others can learn from our losses this early in the year. That attack that I lost the nine in just recently, it got into chain-link, and welded wire (2 different runs). Last years coyote massacre wiped out over 20, plus duck and Goat. That was a welded wire fence, and cattle fencing. They also got into the house after they got into the fence.
No matter how hard you try, there will still be some losses, the the time I walked in to treat the birds with my son, and he told me, "that is a bad rooster, mommy." This conversation went on for a few minutes before I realized that there was a Hawk inside the habitat with us, and it was feasting on one of our hens. She had great camouflage.
We do our best, and often we feel like it is not enough, or that defeated, we failed our chickens feeling, but we always take something new away from it, and learn a new experience. Whether it be a good, or bad experience, we still grow with each. Sharing these things that happen can also help someone else grow with more confidence.
Because our pred are mostly large, or fly, we now have solar powered pred-lights by the main houses, and use smaller heavier gage welded wire, and chain-link. All fences that are not completely enclosed are 6' If they have young enough to attack from above, we have them covered all year, not just for heat. Small bear traps by the bigger houses, and houses were improved to make it more difficult to get into, and we strive to teach the birds to all go in before lock-down each night (safety).
I am not sure what all I can do to keep the new Pea fowls safe, and I am open to any ideas. We are starting with having them penned, and are seeing where to go from here. Food for thought is always a great thing.
Can some of the others on here that have been raised with birds, or are raising birds, and other livestock, now give some ideas for how they keep their birds, healthy and safe? I think that this is a topic that could use some attention this time of year.
I went to trim the ultra fluffy butt on my Blue orp girl and found mites and what looks like these white balls attached to the base of the feathers!! 
I dusted her heavily in DE. And I think I remember reading somewhere about this thing called gleet? But I can't remember how to treat, if thats what this is.... any advice. Ugh I feel horrible now.
