I am really interested in this post, please keep us informed with photos as to how it turns out. As for the white feathers maybe you have a pied whatever x orange breast.

From experience E Orix those white feathers,or i should say partial white feathers are from diet or lack of a good diet.

Are white feathers a sign of low protein in their diet, personal opinion not all the time.
Problems can occur if say kept inside all the time and fed one type of seed.
Live food is not the only way for birds to get protein, check out Plain Canary.

to feed the quick growing chicks at the rate required.
White feathers in Orange Breasts have occurred for years, could be diet, could be the blood line,
could be inbreeding.
Removing live food from their diet for a time should not create a problem. If it did
there would be all sorts of trouble after an austerity period. A chocolate diet to bread and water
over 21 days doesn't seem to stress them out.
What it turns out to be will be of interest, as for being fertile there are several ways it could be,
both fertile, both infertile, male fertile only or female fertile only.
If able keep the photos coming.
