Don't read too much into it.
The best thing about gender-signs are that they are not set in stone. I see why you think that they can be roosters, but I really truely think in my gut that you have hens.
Faces are clear, crest is although in that uniformed shape, very poofy. Body shape is right for a female. Saddle feathering is not too long. I wouldn't worry about the tail. Nothing else fits. Penny looks almost identical to my Zuchinni. Coloring will vary from bird to bird. Zooks is the same color as Penny. I agree that if you had a rooster, you'd be seeing more signs. But both look likes hens to my untrained eye. BTW, without hijacking, do you have any pictures of this Sultan you mentioned?
