I didn't have anything to set it. It's just healing. She's got a new beak growing in, so that's helping a lot. Here's the update on her from today's beak filing:

She's doing well, though I think her top beak is still receding. I'll know better when I file her beak again. The crack on her bottom beak seems to be doing better thankfully. Thanks for asking. :)
