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.
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".)
