I have 4 chicks that I got from a kindergarten class, born April 21st. I know one of the white ones is definitely a roo. The other 3 I am confused. The buff? The easter egger or americana and the last white one I have no idea. Since they were all hatched the same day. The white one that is a roo has a much bigger comb and crows. So I am thinking the other white one is a hen? Any help, I can't have roos in my neighborhood.
