So i bought an albino female for my lonely male budgie and from looking at her bottom i can say there is an egg and its most probably fertile as she was with a male. Currently she is in quarantine with nest box and cuttlebone. Will she care for that egg or abandon it? Will just this egg be fertile or the next egg will also be fertile ? Also even though she is albino she has greyish beak. And she is also shedding feathers and has some blood mark above her cere which is light blue(should be brown right?). Please help!
