Is sex link coloring 100%

[meathook]

Just curious I have a sex link that is the right color but noticeably bigger than the others with bigger feet and comb.

There is no standard for sex-links since they are cross bred. I have several hatched the same day and a few are nearly twice the size as the others.Mine are all black sex links in there now some are solid black others are the red and black but all are pullets.
