Cayuga ducking sneezing??

[Sublime69]

I have 4 Cayugas and 1 Pekin ducklings. They are about 2 weeks old. One of the Cayugas seems to be sneezing. Is this something I should be concerned about??

Do your ducklings have a waterer where they can dunk their whole heads in? They need to be able to clean out their nares.
