OK....so now your all going to think I'm crazy but it worked!!! I had something similar to this happen,
I went to my local beauty supply and bought nail glue and acrylic powder like they use when yu
get your nails done. I got a warm towel and layed her onher side, and cleaned her beak off with a qtip
and alcohol. Took a tiny drop of glue and placed it on one piece of beak then held it together( b carefiul
or you could end up gettin glued to the beak yourself) then i put more glue over the crack and carefully
sprinkled the powder on int,little more glue, little more powder...and i built the beak back up. used a soft
file to smooth it out, (she didn't like that part to much) but it worked!!! and it's held up and she's eating fine.
Good luck....just take yur time..
