hmmm I don't know what she is. I THINK grass keets are a type of Bourke?
She really does look sooo much better. She looks happier..and even PROUD. Good job!
I know we say it alot here, but do you know how important Vit A is for healthy feathers? Will she eat veggies? Like sweet potato and or carrots? Or try some crushed red pepper added to her seed mix?
Nekton makes a bird vitamin specially formulated for feather growth. It's called Nekton Bio. http://www.arcatapet.com/item.cfm?cat=6165
I know it's pretty pricey, if you get some you might want to shop around for best price, but Nekton products are very good and I think little Polly would benefit from the Bio.
Thanks for the update and the new pic. Makes my heart happy to see how much better she looks and feels
Keep up the good work
