Wow this is way late.
by like 6 yrs.
but I am insulted that you would purposfully breed feather duster budgies as they have limited movements.
i hope you sent them to a real safehouse.
not a fake one.
When people claim they breed red budgies i just get angry. perhaps someday, but so far we have pretty much very color exept orange and red. Those breeders just need to sell budgies as budgies.
Try feeding her less seeds, and until she looses some weight clip her wings. pellets and veggies are good, no more than 20% seeds, not too many fruits.
