This was all on @Shadrach 's advice & instructions, he was immensely helpful!I put a tiny drop of gel first on my finger and swiped the top of Hazel's beak that way. It made a thin smooth gloss and perfectly filled in the crack. I had gently filed a little bit first, so she was somewhat conditioned to getting touched there. She did not like the superglue at all, I believe it was the curing fumes, though some may have gotten in through the crack. That quickly faded and I blew gently from behind her to try to keep any fumes away from her nares. It worked really well.
