I just thought I’d post an update for those researching on here, wondering how their chicks might turn out based on looks or behavior. Elsa the white bantam became a white Cochin rooster who was getting mean and aggressive to people and birds at 12 weeks - he is no longer with us. Dinosaur became a dark Brahma bantam rooster who took forever to develop a red comb and didn’t act roosterish until Elsa was gone. Charlotte turned out to be a pullet, somewhere in the middle of the flock totem pole. Fauna, now known as Stripey Pants, is a rooster although he is still lacking a big red comb and no crowing or anything, but I see no way a female Cream Legbar could have that many barred feathers. So in my case, three out of four of my boisterous chicks were indeed boys.
