Hi everyone, I have a mille fluer hen that I have had for about a year and a half. I have always heard her sneeze a little bit but she acts perfectly fine eating and acting normal. I thought maybe just allergies. Recently she has been sneezing a little bit more and now has a bubbly eye that is sometimes crusted shut. She is still acting normal eating, vocalizing and scratching and pecking around. None of my other birds are affected and like I said I have had her for a year and a half. Any ideas what it may be and what I can do for her?
