Thank you for the replies. I did give him a week of antibiotics and steroid drops, as well as regularly washing his eyes out with saline. The "bubbles" have since dropped off and he seems to be able to see out of his left eye, but the right one still has a small white line of stuff stuck to it. I will keep you posted.

Thank you FrenchBet for the information. I was not aware of that.
IveGoneQuacky, (love your name by the way!) I do not have an update on this issue because sadly, a predator got the little guy right out of our front yard. I have never had the problem again with any of my other ducks, but if I do, I will take them to the vet and update this thread with any info.
Thank you to everybody who helped out!
