It depends on the chicken itself cockerels are pretty un predictable when it comes to maturing but even with the unpredictability the combs look awfully red and suspiciously big.It depends on the breed but my cockerel had a red comb as theirs by 6 weeks of age. By 13 weeks, it should be much bigger but again I am not expert... could depend by breed, just guessing based on my own experience or pictures I've seen.
