Look at the combs and wattles. Those birds that have combs/wattles getting bigger and redder are cockerels. Those that have combs/wattles that are unchanged are the pullets. Pullet comb and wattles grow larger and redder when egg laying time gets closer; in 3-5 months from now

the second pic and the one in the background of the third pic are cockerels.
