softbills are so precious. I have 2 cockatiels that we hand fed at 11 days old we started. They are now 4 years old, and doing quite well. We feed them nothing but Higgins "Safflower Gold" it is the best. We have a man that sells hay and stuff, he orders a 40 lb bag for us and we divide it up and refrigerate it, lasts a very long time.
Good luck with your baby. They are fun to raise.
