I have a female lutino that had a bald spot that i know that is normal for her mutation but these few weeks she started to loose her body feathers and many of these were growing under the skin. Leaving her body almost bald that if you move her wings seeing her from her back she is with no feathers. Also she stink like bread so maybe i was wondering that it could be a yeast infection in the feathers? I don't have any cockatiel with this before so any information would be great of how do I treat her. She lost her 2 clutches due to yeast infection that's what made me think about it.
