I dont know if this is much help, I am in a similar gender guessing state with my golden laced wyandottes. The "rooster" had a comb that had 5 finger like projections off the top. The two that we believed to be hens have bumpy rose combs. But now I am being told that they are roos. (the one with the biggest rose comb is my avatar picture). I am new to chickens so learning their gender based on the comb is new to me.
