Of course #1 is hoping they produce some babies.

Out of interest, I read about the color genetics of parakeets. Very interesting. She is a Double Dominant Pied White. Lupin is a White (blue) with one dark factor, making him cobalt blue instead of sky blue, and he also has a violet factor, making him purple-ish, including his feet. Info said the only color you can actually see the violet expressed is in a cobalt bird. Anyway, if they did manage to hatch some eggs, the babies would all be white-blues of some sort. No chance of yellow based birds since that is dominant.
