Just curious but did you reattach the end of your thumb or where you trying to seal it with super glue? As that I don't advise. And as I've said the point isn't too seal it shut it's to hold the skin in place while she heals up. More compairable to stiches than a bandage.
I think you will find however that maximizing healing time (and also reducing the water loss from such a big hole) will be well worth any risk of stinging. Also the wound still needs to be flushed, sanitised, and moved into position which is all at the very least uncomfortable. Not to mention your hanging skin drying out is very painful in its self. If you really want to avoid all discomfort the bird would need to be put down or taken to a proper vet who can numb its pain and stitch it up.
But if she/he is doing this at home and is trying to save its life then she needs to set that skin back where it belongs as soon as its clean. Get some antibiotics for it, and keep it warm and hydrated at all times.
