Thanks for the reply, that's exactly what I figured, these 3 on the other hand, are freaks of nature. Lol. Same age, about 4 weeks, 3 different combs going on. One faint Pail yellow I suspect is a pullet, another the exact same and shape and color, but with a black comb, and the one looking at the camera has a black comb, way more developed than the other 2, I suspect this one to be a roo.
