My Wyandottes were straight run, but I'd hoped out of three we would get one hen. When looking at the three of them together, one looks very "roostery" stands erect and even walks "cockily", longer tail, rooster-shaped body, larger, redder comb and wattles. The other two have red combs and wattles, but very little tail feathers and hold themselves more horizontally when walking. The two more matching hens have similar feather shading and patterns, while the other "roostery" one looks a bit different. They all play-fight with each other and the other pullets with raised hackles and I don't know if that is a rooster trait or not. I either have one cockerel and two pullets OR they are all three cockerels and two of them are just sharing traits compared to the other. Every day I try to get a good photo of the three of them together for easy comparison. I will try again later today when I get home.My Wyandotte looked exactly like yours did. He's now 12 weeks old and growing saddle feathers and getting into all sorts of trouble. From what I understand though, Wyandottes can "bloom" early and really freak you out. Were yours sold as pullets? Surely your luck can't be that bad.
