As donrae said, maybe in another month or more. If its a roo, the wattles and comb will begin to get pink and start to grow bigger. as he/she grows older and starts to get their adult feathers, thin, slick feathers will come in on their hackles and saddle if it's a rooster. Hens will lack these and will usually maintain pale, almost nonexistant comb and wattles until maturity.
