Grapes are not something a bird would be willing to try at first. It took my birds 2 years to even think of biting the grape! They'd rather play soccer with it than eat it.

You bird NEEDS to eat veggies and other *people food* along with seeds and pellets to get the proper nutrition she needs. Start with broccoli, peas, and romaino lettuce. (dark leaves, not the *ball* kind). Iceberg lettuce is mostly water and doesn't have much nutrition. You need to be patient and offer the bird veggies until she gets it. Broccoli is very nutritious and a veggie most birds LOVE. Its the veggie my birds started with and until today, its still there favorite. One she gets used to the greens, you can try offering her carrots, corn and other veggies. NEVER give her avacado as that is one vegetable that can kill birds.

Other people food that's good for them is whole grain bread. White bread is not so good for them, as its not so good for us, so give her whole wheat or whole grain bread. Birds also love popcorn. If you want to give her popcorn, it should be just popped corn, with no added butter or salt. If you need any more help, feel free to ask. You should have posted this in Pet General though because I would have seen it earlier.

Ps. You never did show us pics of your birdie did you?
