The neighbors (where this bird came from at about 8 - 10 weeks old, I believe), are of the opinion that "Smokey" (below, in the middle with the gold leakage) is a rooster. The only one to crow has been the white one, and only once. The barred chicken and the black one that is in question both started "honking" a couple of weeks ago. Any thoughts on this? The older two birds are probably about 16 - 18 weeks and the younger two (the black one and the white one) are probably around 12 - 14 weeks. The three pictured below do a lot of fluffed up posturing with each other, but like I said, I haven't heard any crowing except for the one time.
