It's easier to tell when they are younger than 5 days the pullets start growing in their wing feathers faster than the cockerel's. you still maybe able to tell look close at the feathers on their wings or post some pics maybe I can help or you'll have to wait for a crow or egg.To the chicken people in this thread (yes I know it's the duck thread lol): how and when can you tell the sex of young chickens? What do you look for?
