After keeping my the little Burke Parrot alive for nearly two weeks he past away. It was upsetting as grew attached to Buddy but what I can take from the experience is that have gained some skills and gear in hand rearing for other bird abandoned by their parents or if I choose to hand raise a bird.
After cleaning out the nesting boxes from the Bourke Parrot cage I found a lot of mice droppings to the right hand side of the nesting box. I suspect the mother pushed the chicks out because of being hassled by mice. From what I have read this is one of the common causes bird will abandon young.
I believe Buddy had some injuries from the fall from the nest. His leg was obvious but I'm not sure if further injury had caused him to pass away.
I have named my abandon Bourke Parrot chick "Buddy". I has become obvious that she has an issue with one of her legs; I'm not sure if this was the reason she was chucked out of the nesting box or something that happened in the fall.
I'm now a lot better set up with a plastic box with a reptile heating pad taped to the bottom. This now allows me not to worry too much about keeping her warm and just focus on feeding. I'm roughly feeding her every four hours and during the night I feed her just before bed, once around 1 to 2am and when I wake. She now chirps when she hears me mixing her food with the teaspoon anticipating the feed.
The thing I have definitely noticed about "Buddy" is that she is a fighter and has a determined will to live.
