Is she plucking or molting horribly

She's 1 year old at the moment. I've had birds for almost a decade. I also have two other birds. I've never seen a molting as bad as this so it makes me think she could be plucking. She's with me pretty often throughout the day but I never see her pluck. It's making me question if she's doing it in her cage at night instead.
