Hi there

I'm no expert, but I think what you've been told
about the turquoise budgies matches what I've
heard. You need a sky blue budgie with the YFII
added to the mix. Another sky blue would keep
the blue at the same intensity, versus the dark
factor in the cobalt blue. With a little luck,
the yellow will alter the blue to that lovely
turquoise/teal color

Somebody, please jump in and correct me if I'm
wrong?
