New breeding oair

[Fraza]

New breeding pair as I found out the one I had coco lined up with was too young

Hoping to get grey pearl from these two as the male is a black Euro and the female has a grey pearl farther and fawn ginger mother so hoping that the ginger makes the black chicks lighter to make a grey pearl
Any advice will help

Also just one other question anyone know why her bottom part of beak has always stayed yellow ish not gone fully white could it of been a diet from a chick
