Just a quick update.
I filed Bitty's beak to the point where you couldn't even tell there was a problem anymore just by looking at it. But the big surprise is that even now, after 2 months, there's not sign that she even had a problem! Even when she opens her mouth her jaw looks normal.
I guess it's possible that her crooked beak was not hereditary but some type of injury. The injury was probably recent and being young her jaw was able to realign itself one her beak was filed. She's also eating well and is no longer the smallest in the flock.
Regardless of the reason, I'm thrilled!
