I'm sorry for your loss!
I know what I'm about to say is going to sound insensitive, but this is something you're going to have to come to terms with. I think that by not culling the chick, you put her through five days of suffering that could have been spared. A prolapsed rectum is something that is serious, and it was repeating. That's not a trait that ought to be in any flock, it puts the birds through too much pain. Culling is sometimes necessary.
A word of wisdom:
If you want to do what's best for the animal, sometimes death is better than staying alive.
Harsh, but it's a fact of life.
But that doesn't mean you can't give her a nice grave and put flowers on it in her memory.
