Hi, I am new and have a question. I have an Alexandrine female and she is with us for three years. I don't know how old she is. We live in Israel. She laid six eggs this year and now we are entering molting season. I have noticed a bunch of after feathers on her breast on each side of her breast. I took a closer look today and it looks like she has really been worrying those areas and I can see a new live feather stalk, quite thick and exposed. This is the first time this has happened. She is obviously concentrating on those areas. Can anyone tell me if this is something I should worry about. Is she possibly stressed?
She has a clean cage, clean water daily. fresh fruit daily, good pellets which she doesn't like, seeds which she loves. She mostly likes, peas, cooked potatoes, rice and fresh apple.
Thank you in advance. I would appreciate advice.

P.S. Her routine is pretty much the same. I leave her music when I go to work and she is not near a window.
