I would keep a close eye on your bird and make sure she is actually eating. You can do this 2 ways, with a gram scale, weigh her every morning and evening, or check her droppings every few hours-if there is no solid part/green, she is not eating. I have read they can starve themselves rather quickly, so if after 1-2 days there is no green in her poop or she is losing weight, I would switch back to a seed/pellet mix, of mostly pellets, but some seed for 2 weeks, then try again. Always offer greens, veggies, and pellets in separate areas of her cage. Put pellets up top so if she is "lazy" she can get them easily. Try different pellets/brands and try mixing them.
My girls will eat pellets from hand, on their playgyms, in the separate pellet dish, but never
in their "normal" food dish. Crazy Budgies!
