I was going to say they look just like my sex-link Golden Comets too...mine are just over 10 weeks old. Are you sure the roos are really roos? Mine are getting red/pink in their combs and their wattles are starting to show up more. I sure hope mine are pullets and true sex-links!!! I will croak if Lucy is really Lukey!!!
Yours may have a bit more white in them than mine.
