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.
