Yeah, as I look through your pictures again, it looks like the bottom beak is straight and the top is more crooked. Do I have that right?
The top is much harder to correct. You can only go to the quick and no further, and there's more room for that on the lower beak. From my experiences with Little Miss Crossbeak and watching a LOT of videos and reading stories/viewing pictures of lots of other crossbeaks, it seems like those whose bottom beaks are closer to straight do better. The can still scoop up food and water straight on, and once they get food to the middle of their tongue, that organ can take over and help get the food past the glottis and down to the crop. I think this one will not have as much trouble.
Of course, it goes without saying (but for posterity's sake, here it is...) that if you're going to clip or grind down the beaks, you need to have a styptic stick on hand. You'll get bleeding at some point, and you'll be glad you've got that blood stopper! And you don't want to put your baby back in with the flock with blood on her, because then she'll get picked on. As you told me before: the pecking order is real!
Again, you're FAR more experienced than I am, but I'll put this down for future readers: I prefer the styptic stick to powders because it's easier to administer quickly and with minimal mess. But there are good powders out there, too.
