Hi EllaDad,
Welcome to the forum.
Was your baby sold to you as being weaned or did the breeder make you fully aware the baby had not weaned and still needed 3 feeds a day?
Is your baby Ella eating anything on her own? Does she eat the fruits and veggies? Is she on any pellets or seed? Just a bit more info on her diet would be great.
Below is a guide to handfeeding, it does vary for each bird as they do wean at different ages. Two of mine were fully weaned by 12 weeks the other took a bit longer.

It all depends on what your baby is eating to how many feeds she should be having.
I hope the guide will help you, If she is not accepting pellets yet, try them and they can also be slightly moist if she refuses to eat them dry.
Please keep us updated and ask any questions you may have:)
