Hi all. Can anyone help. One of my ducks is looking terrible, unlike my other ducks who all have healthy looking feathers, bright orange beaks etc. I have separated her from the rest. She is breathing very strangly and wheezing almost. I have started giving her 1ml of colloidal silver (18ppm) heard that helps with any respiratory infections. Any feedback or advice. I have attached video. Unfortunately you can't hear the breathing as she won't let me get closer and don't want to catch her again now and stress her out.
