WOW! VERY interesting!!! And thank you for this info. You obviously know more about breeding and mutations than I do. In the last three clutch's we've had ( by other birds ) it was pretty straight forward as to what we would get and really no surprises. This one now is a little different to say the least! Your explanation about Buzz and HIS parents was a major help regrading the lack of pearls on the chicks. I always kinda wondered about Auzzie as even though she appears white (from a distance) the white on her face is a little off compared to Buzz. Again, Thank you so much for your help.
