Well, their comb and wattles will be very different, the comb will be big for roosters and small for hens, roosters will also have bigger thicker legs and hens will have smaller ones. Roosters will have pointy tail feathers and hens will have rounded feathers. If you have crested birds, the crest will be bigger on the boys

thanks for your reply. would i already be able to see the differences at 15 weeks? we have barred rock chicks and black star chicks.

Barred Rocks you can tell very early and same with the Black Stars. Barred Rock roosters will be much lighter in color. As the other poster said comb will be bigger and redder and legs much more stout. I believe Black Star (sex linked) roos will also be barred. So they will look the same as the Barred Rock roos.
