What can this baby be? (Pictures taken last night at 16 days old.)
The father looks to be blue base with yellow face type II which causes the green. You can't tell from the picture but his wing tips are yellow with white on edging.
The mother is an albino. Red eyed white.
A previous clutch had 4 babies. 2 albinos, 1 albino with yellow face type 2 (cremino?), and 1 blue opaline with yellow face type II. The blue is suspected to be a boy.
The other baby from the above babies current clutch looks like a blue. It has no yellow face or white/yellow wing tips.
