Spurs are usually one of the last things to develop, so are not a reliable indicator of gender of an immature bird. Spacing between the pubic bones is one thing to be checked--if narrow & tight almost certainly male; if loose & wide almost certainly female. If narrow & loose or wide & tight, could be either.
As has been mentioned, look at hackle and saddle feathers. Colour patterns can differ between genders (males get different colours on the shoulders and saddle, females on the breast) for some varieties. Next time find a breeder who will guarantee the gender (by exchanging any males you may accidentally get).
