Why are you pulling for a girl so much? If I was you I'd be all about a boy. first because you have three birds and more girls then boys usually ends in death whereas more boys then girls is usually a happy little home. Also, boys are mellower, easier to train, dont really enjoy biting, and are much more pleasent to listen to. I was really hoping Nouba was a boy for the longest time lol. Also you don't have to worry about eggs wiht boys even if girls havent mated they lay infertile eggs sometimes causing potentially lethal problems...
with the description you just gave I'd say she's a recessive pied boy
