I think you mean Conjunctivitis which has really affected the wild house finch population.Pukasand wrote: Awww. You did the best you could. I know there is a disease affecting wild finches that resembles that eye problem. Did the previous owner subject them to wild birds? ie: outdoor aviary or an 'adopted' wild bird put in with the flock? Hoping the rest of your birds are okay. Keep us posted.
