A male chicken at that age would have very large red comb and wattles. It would also have long sickle feathers (tail feathers).
Your chicken has no signs of sickles and the comb is small
At that age both pullets and cockerels will have combs. Males develop combs and wattles at a younger age, whilst pullets (females) develop them later. Around laying age, the pullet's comb and wattles will redden. That's probably what you're seeing
