Karen, sometimes, they just get stuff crammed in there from feed or dirt outside. I just had to scrape out my banty Cochin's nare on one side, which was completely closed up with what looked like just feed packed in there. The other side was completely clear. I have to do that with Zane from time to time, too. They can't clean out their own and I've seen folks who have had birds with a corn kernal crammed up in there and other assorted things. You just have to dig it out, which is much like trying to wipe the nose of a struggling toddler, LOL.
