They both have deep purplish ceres, but CA2 has a hint of white, so I'm not positive about that one being a boy.
Any of the Daniel and Maude chicks that are not opalines are automatically boys. Opaline causes body color to show in between the wing bars, so I will let you figure out which of them are boys or girls.
The following chicks are from Seaweed and Tiffany. Every one will automatically be opaline sky blue, so we won't be able to tell gender based on opaline with this clutch.
STi4 has to be a girl, due to the albino gene being sex-linked. But you can already tell anyway by the amount of white on the upper half of her cere. Albino girls are good for learning on, because no matter what kinds of changes the cere goes through, you know it is always a girl. I've been able to observe how one chick can go back and forth between looking male and looking female at the different stages, which gives me proof that certain shades of baby cere don't tell gender at all.
Since I'm also able to determine gender beyond doubt with Daniel and Maude's chicks, I have compared their ceres, and some of the boys look exactly like the one girl. So that also verifies to me that at some stages, boys and girls look exactly the same.
On the next few chicks, I just can't tell gender yet. I will have to wait until the cere becomes a more solid pink color for boys, or until it develops a lot of white, for girls. The last one, of course, is the other albino girl.

(By the way, the lines of pigment on this one did become more irregular, and it is a spangle. Whether or not it is also recessive pied is still up in the air. And it is turning yellow face.)
I thought I would throw in some pictures of the Bourke's Parakeet chicks today, too. With that species, the ceres don't indicate gender at all. In fact, with some of the Bourke's colors, it can be impossible to tell the males from the females.
Fortunately with these parents, the sex-linked opaline gene comes to my rescue again. Eagle, the father, is opaline and the mother, Inga, is not. So just like with Daniel and Maude's chicks, all the opalines are automatically girls, and all the non-opalines would be boys. It looks like both of these babies are girls, because they are pink. (An opaline is called a "Rosy Bourke".)

They are only one day apart in age, and almost identical, but I'm guessing the one on the right, which has a larger tail, is the older one.
