Hi Zork,
A good diet is VERY important during a molt. Feathers are made of something like 88% protein, so an added protein source will help during a molt.
Will she eat eggs? Hard boiled eggs are a good source of protein. Be sure to boil for 20-25 mins to kill any bacteria/salmonella. Chop the egg up really well and see if she likes it. Only leave egg in cage for a couple hrs tops tho as it spoils quickly.
Adding an egg food mix is also an excellent way to up protein and increase nutrition. I get this one https://www.birdsupplynh.com/catalog/pro...e5414d254c30ed8
IDK if that link will work. You can find egg foods at most pet stores.
