Now that's a tough one. Try feeling the bones underneath them that form a V shape, if you feel a large gap at their "peak", then it MAY be a female, to accommodate egg laying. Males will have them closer together and sometimes touching, but then sometimes just as wide as females. This is not "sure-fire", I don't know of any way that is, other than watching which one lays an egg!!!
Males will coo more, dance around more, showing off to the hens, puff up their 'chests' etc. just making a show. Sometimes males are larger, but rarely, and that won't help much now.
