I have 4 ducks and a goose and I went to let them out the other morning and my Pekin duck wasn't opening her eyes. Then later that day my runner duck had the same thing. When they barely opened their eyes they were very foggy and goopy. I separated both of them from the other ducks. Today the Pekin won't even open her eyes and the runner does a little but her eyes are still very foggy. Besides the eye thing they are doing fine, eating, drinking, etc. Please help!!! Thanks in advance.
