Chiclet seems to be starting to wean herself now. She has found the millet spray in her cage. She can crack it open and eat it now. I held up her pellets and she took one of them and played with it in her mouth. She's on her way!
I would try giving her the soft veggies they will be easier to eat she might just pick at them the first couple times but she will quickly get it, are you giving her soaked pellets? You don't have to wait till she is fully weaned onto the pellets you can offer both
I would be putting EVERYTHING in her cage now. A little bit of millet, a bit of seed, some pellets, maybe some dry cheerios (cereal), a little popcorn, try her on tons of different veggies, etc. Now is the time she'll be most adventurous with new foods, so take advantage of it.
