I don't really think it is a health issue, I mean she doesn't appear or act sick. Even if I drove a hundred miles to see a vet I don't know which vet I would see. I mean I don't know who is a good vet, who is experienced with hormone issues, etc. 20 years ago I was taking her to a vet here. Each time they wrapped her in a towel so she wouldn't bite or fly away. When I got her back home, she was so traumatized, she was mad at me for a week, so I stopped taking her. For 23 years she has never had any kind of sickness.
Food, ok I feed her Pretty Bird Medium Hookbill, premium bird pellets. I raised her from a hatch-ling. When she was a baby, I fed her pretty bird baby formula. At this point besides food that I eat she won't eat anything else.
Cage, she has a 22" round cage about 6 ft tall. 3 of which is her living space. I had a bigger one for her at one time but she didn't like it.
