Sunny and Sky have done their first molt, so it's a little easier to guess at gender (cere color, band of flesh on their beak). Looks like Sky is a hen, no real surprise her cere was always iffy. Hard to tell in lutino birds (yellow) but it looks like that's lavender with a blue undertone, so that's at least one male and one female. Breeding will be a thing. Next year, when they're mature enough to be good parents.
Also, I love how they look against the purple wall, those colors just pop.
