Guinea fowl were my first poultry, 15+ years ago. Many years ago, a farmer friend was going to sell me a "hen" that had the large, cupped wattles, but I didn't believe it was a hen until he caused her to puh-track. Since then, I've had numerous hens with large, cupped wattles. A couple of other ways you can determine male/female once they are adults; the males will stand "taller" with their bodies slanted downward on the tail end while hens backs are more vertical and in mating season develop a bustle; hens profiles are USUALLY more refined--the cere, which is the red band surrounding the nostrils, is less prominant (but that's a bit difficult to tell without quite a bit of practice). Your males that puh-track are HENS. Only the hens are able to puh-track; the males can only make a one-syllable sound except for some of the very soft sort of cooing they do at night--you have to be right next to them to even hear that.
