Goldie looks like an Easter Egger and the 2 dark chicks look like my cuckoo marans when they were babies. All still to young to tell sex though. I would wait until they are 4-6 weeks and then you can get a better idea of sex and breed .
There's 3 dark chicks I believe the first one is a rooster, because of the tail. But I will wait and see. Do you know anything about the very first one?
I got her from my work. (a dairy farm) the owner told me she was a baney, her mom is like a light brown color with a black tail. Smaller than a Plymouth Rock chicken. She could also be crossbred. Her comb? Im guessing you mean beak, which is like a orangey yellowish color with a black stripe on it.
Her comb is the thing on top of the head. Depending on size and color, you can usually tell if you have a boy or girl.The chicks may be too young to have one. They are cute whatever the type.
I see. All of them still have fluff. But the 3 black ones and Goldie have like the beginning of their beak ridged, which was different from my oldest one. I'm guessing its just the breed difference.
