remember although your origional breeders may have been "albino"-ish, albino parents don't always have all albino babies. I had 2 albino mice once have a litter of 13, all 13 where solid black, now there are colors and patterns coming out.
I also had a fawn hooded dumbo girl that was bread with a black hooded dumbo male, and some where black hooded, some fawn hooded, then I got a couple blue, and some champagne. the next generation gave me some hairless too.
