I’m so upset…

If you want to try something anyway... you might go out with a good flashlight (spotlight if you have one) and light the way down for them. Maybe, take some treats to help encourage them down.

I've done this quite often and mine came down quite readily each time. To be fair, they were hungry the first time I did it. And after that, they had done it before, of course. But if yours are too uncomfortable, I would think that would encourage them down as much as being hungry would.

Good suggestions here.
I'll just add, my method to get a chicken down from a high place or out of an awkward place is to get a really long pole. Hopefully not too heavy, and wood is better than smooth plastic/metal although it might do in a pinch.
Then extend your pole out to the chicken, keeping it balanced and steady. Move the pole just in front of the breast bone, horizontally, so the end is just like a roost bar. Nudge them gently in the lower breast, or tuck the pole under a little and lift them a bit, that sort of motion wakes them up.
Then they tend to get interested in the roost pole that's higher than their current one. When they step up on it they will flutter their wings to balance and your job is to smoothly lower the pole to the ground without disturbing them off of it or making the roost angle too steep to grip (why wood is better).
I know my detailed explanation makes this sound really hard but it's easier for me than climbing, lol.

Be careful not to poke them as you won't have a enough feel for the pressure on the other end. And some are really slow to wake, requiring repeated cajoling.
But if yours are out in stormy weather uncovered it's likely they aren't all the way asleep anyway.
