I breed budgies in my aviary and I recently hatched a bunch of four. One of the budgies must be aggressive because 3 have sustained injuries. 2 have healed up nicely with some medication, but one received injuries to its lower beak. I gave it some antibiotics before going away for 4 days. I came home today to find the swelling gone, but one side of the beak is disconnected from the chin. I was planning on hand rearing one for the first time after owning budgies for a year and Im going to do this one. What will happen with the beak? He doesn't make any noise whatsoever that I have heard, while the others in the nest do. He is about 2 and a half weeks maybe? Im not sure how to upload pictures, this is my first post. Also any tips on hand rearing will be appreciated.

Hi There, Could be another hen getting in and trying to kill the babies as they will do in an aviary situation.

Personally I would assess the chick and if I thought that the beak would prevent the chick from eating properly when older I would put it down.
