Hello, new to board and new duck owner. I've had my ducks for 2 weeks now, so they are about 2 1/2 weeks old. I have a Blue Swedish whose right nostril is plugged. It is solid and looks almost like a scab. Cannot pick or wipe it out. He/she does have water to dunk bill/head but it hasn't cleared. Most of the time he/she seems to breathe ok. If they have swam a lot, may appear winded, but I'm concerned and still novice with ducks so I want to make sure I am doing anything I can to help.
