I just got my baby but she was 16 weeks...about the avg. age for an ekkie to be released to an owner but some breeders here in the states will hold them even longer--up to 7 months. I know that AU breeders often sell them very young, not sure why but i wish you the best with your new bird. I am still feeding mine formula (by spoon) at night. She is not fully weaned but she is eating a chop mix in the morning and her dinner is fresh fruit. I would encourage you to feed formula for the next few days just to insure your bird is getting enough nourishment while you make the transition--past the panic stage.
Chop small. Babies are just exploring food and cannot manage is ably as an adult can. My baby still cant manage to hold food with her foot, she can only take a bite of something, the rest will fall to the ground. Even with almonds, she cant manipulate it in her mouth (the whole almond) so small is best. As far as consistancy, think runny crepe batter or a slushie for texture, slides down easily. Temperature is important--when they are young the temp of the food influences their body. I would switch to a bent spoon as soon as possible (personal opinion here) so that your baby has more control over the feeding process. They should be able to gulp on their own at this point so you will have fewer potential issues with aspiration.
You may also want to supplement the fresh veggie chop with small (cockatiel size) pellets mixed in as an inducement to eat. While WHAT they eat is important, at this age so is HOW MUCH they eat. Until you get things sorted, I'd go with quantity over quality. A week of imperfect diet wont hurt your bird nearly as much as being malnourished. FYI, my girl is nearly 5 months and is still not weaned, though she eats a healthy amount on her own. I keep up her formula as insurance that she's getting enough to eat because she can still be picky about what she eats and doesnt always eat as much chop as I think she should. Also be cognizant about proportion of proteins, fruits, veggies, and pellets--but that can come later. Best of luck and welcome to the forum. I have found it to be an invaluable resource!
Someone mentioned housing. I'd keep your bird in a smaller cage (sleeping cage) for another few weeks. Babies are clumsy and dont have great skills--yours is probably just learning to perch. They fall. Falling a foot to the floor of the cage is much less harmful than falling 3-4 feet. Wait until the mobility is greater before you move to an adult sized cage. I just moved Liesl to her "big girl" cage two weeks ago, and she still misses a step every now and then and crashes. If you dont have a small cage, pad the bottom of your cage with towels so if your baby does fall it has a nice cushion. Not one towel, TOWELS plural. Think as if it were you.
