I went to stare at my beautiful Mandarins this morning and one of my males was isolated with frozen feathers and his bill is bleeding. He looks awful! Does anyone know what is going on with him? It is really cold outside. I brought him in to thaw out but am not sure how long to keep him in or what to do from here. It is Sunday and we have no vets that I trust around here as far as ducks go. I don't want to keep him in all winter either.....any suggestions?
