My Quaker Mimi that I have had for around 5 months now, (she was 3 years old when I got her) is starting to preen a lot over the last 2 weeks now. I just want to know if that's normal as she's losing a lot of feathers, I've heard of molting with birds but from what I've read it usually only occurs around august. Also she eats a ton like every hour but she looks skinny and underweight. I did the breast bone test to feel for the crest and it feels sharp to me. I would like some advice first before I take her to an avian vet for them to tell me it's nothing to worry about. Also there are a lot of white flakes after she's done preening.
