Sorry, but I dont understand things like brindle and masked or whatever about budgie mutations, I only use colours like blue and green. I dont understand the other stuff.
I was wondering what colour babies I would get if I bred a male blue budgie with a female grey budgie?
Probably about half blues & half greys. There could be different shades of blue depending on what shade your birds are and also you could get different wing patterns. If you could post some pictures it would help but even with pictures we can't see if the birds have any hidden genes
Your hen is an opaline grey and the cock is a greywing sky blue. As the opaline is a sex-linked mutation and the greywing is a recessive one the chicks will have a normal black wing pattern unless one of your birds has hidden genes that match the other's mutation. You should get grey and 2 shades of blue in the chicks
