We're assuming, at this point, that we're going to have to clip wings across the board just to have any peace of mind--especially with the turkeys.
Please, no chain-link horror stories, unless they're cautionary tales in which disaster can be AVERTED!

(In other words, YES to "If you have chain link, you should do ______", but NO to "Never have chain-link; it's deadly!") I say this because our ENTIRE 5 acres' perimeter is fenced in chain-link, and there's nothing I can do about that.
The only trouble I've had with horses and fences over the years has been when there has been something on the other side that caused a problem...like someone else's horses fence-fighting with mine, for example. What I've done in those cases was to build a second fence several feet inside my own property line, and add hot-wire.
Victor, the stallion (who is scheduled for gelding), did once manage to put a leg through the top cable of a low chain-link fence, and had to be cut free. He wasn't hurt, but it scared me to death. We got rid of all the mitigating circumstances in that case, and did our best to make sure the accident can't be duplicated, but with horses, you never know.
We're in the process of getting rid of all but one (or possibly two) of the horses, since this place is just not set up for horses.
Back to the birds...would leaving the "prongs" on top of the fence discourage them from roosting up there? Probably not, I'm guessing. I'm always amazed when I read all the posts from people who have no fence at all but allow their birds to free-range. That would make me a nervous wreck!
My husband is not really happy about the appearance of chain-link around the house, but there's no other option that we could afford, and I wouldn't want a wood fence because that would limit visibility to the rest of the property. Back when I first mentioned just putting up a fence like at my last place (5' high, RR ties at corner, 4x4 posts and woven no-climb horse fence), he had a fit about how "ugly" that was and how it would ruin the resale value of the house. So, it looks like it's either this or nothing.
If anyone has any safety issues that I can address regarding my existing chain-link fence, please tell me. Whether we get this one or not, I already have miles of it in place that isn't going anywhere.
