Last night when I put my babies to bed everyone looked normal but when I went to put everyone outside for the day my lavender gander's wing was droopy and turning out Is it possible to develop angel wing over night? I have seen my gander and goose pick on each other once in a while, could she have pulled on it and did this to his wing? I kept him inside this morning and he is in the bath tub having a bath and I am going to wrap it once he is done and dry. Should I keep him separate while the wrap is on so my goose and ducks dont pick on it? Thanks for any advice!
