Looks like a minor scrape (red circle) that will probably heal up o.k. on it's own. She may have scraped it on some wire fencing or a feeder. If you wish, you could paint the scab with a little Iodine.
The tip of her beak looks cracked (red line), it may mend on it's own, possible that the outer layer may peel off, hard to tell.
You can try mending it with super glue and a piece of tea bag if you wish (instructions in this
LINK.)
I've found molting birds usually don't eat very well or they go off their feed. A sore beak is going to make that a bit more of a challenge. Try offering her some wet soupy feed, bits of scrambled egg or fish to entice her. Hydration is most important of course.
If she's really struggling, then direct dosing her with a poultry vitamin like Poultry Cell for a couple of days may also give her a boost.

She seems to shake too at times.. like a shiver? Worried this is more than a normal molt..
