Hey everyone. I have another question. The little duck I have with a deformed beak has sneezed and clicked since I got her, I had assumed that it was because of her beak. Now my other two who are generally healthy are sneezing and my welsh is yawning often. I tried giving them water to dunk their heads but it hasn't seemed to help. The welsh does have visible dried crusty nose gunk. What antibiotic would be safe to add to their water and what dose to treat a URI? They are about 5 days old.
