Hoping someone can help. We have a small flock of fourteen birds. Yesterday, we noticed one of them, a small Silky mix, had her eye closed. It is not swollen or obviously discolored. We were not sure if this was the result of being pecked by another bird. Today, we found two more birds with similar symptons. It has been extremely cold for the area, with temps at night in the low teens, so this may be a factor. Here are the pictures. ' We are guessing this is some kind of infection and would like to know what we need to do to treat our birds. Thanks for your help.
