Egg laying has more to do with length of daylight than temperature. Fourteen hours of daylight is good for laying eggs. If you are impatient you could put a light on a timer in the coop. Start off by having light come on a half hour before dawn and gradually have the light come on sooner. That would stimulate your girls to get into egg laying mode. You could also let nature take its course. My pullets that hatched in June still have pink faces and combs. At some time between February and June I expect they will start to lay. As to the rooster, he is randy and will keep tring as there are no mature girls for him.
