I just got a duckling yesterday and it had a really runny nose. I did a little research to find out what to do and gave it a warm bath today so it could play and dunk its head. It went really well, but the nostrils were clogged and not coming unclogged. So, I looked at what to do about that. I tried cleaning them out, but it didn't work! So, I took a really good look and realised they are sealed shut! It's like ear piercings that have healed up. You can see where the holes should be, but it's solid. The duckling is breathing fine through its beak, though. It doesn't seem to be bothered. I'm still worried, though. Does anyone have any suggestions? I don't know if this is really vet worthy or not since it can still breathe fine.
