Hen/rooster height?

[BokBokChicky]

We just got 8 chicks a month and a half ago, 3 roosters and 5 hens (ones a silkie but I have no clue how to sex a silk and the rest wyandotte/silkie mixes). They're so young but the roosters are almost as big and tall as my adult rooster! So my question is, how big and tall do wyandotte/silkie mixes usually grow too?

You'll get better responses if you can post some good pics of your new babies. A good profile and frontal of the head and a full-body side shot would be very helpful. And your babies won't be hens and roosters until they're a year old. For now, they're pullets and cockerels. They're roughly the equivalent of human teenagers ... and just as ornery!
