Ok so I noticed tbe other day one of my ducks was whistling in the nose. So I gave him a warm bath and he had some down feathers stuck in there. Got them out and he is fine. Then yesterday my other duck starting whistling and today not only is stl doing it but is now quacking. She is acting normal. No discarge or anything. She just had a warm bath now and played in the water. I dropped peas in to get her to dunk her head more then normal. But I am at a loss. This isnt showing signs of a RI. If there is something stuck I cant see it. There still pretty downy right now. About 3 months old. Any ideas??
