What is wrong with her nostril?? I've tried to scrape it out before but it's hard, like bone. And the little bump at the bottom is like a flesh sac. Her nostril has been blocked for a month or two, but it has gotten worse in the past few days. The bird is perfectly healthy, laying like a champ, eating, raw unfiltered ACV in the water, doesn't sound raspy, good color, and her other nostril is totally fine. Should I be concerned? What should I do?
