OK, I have two silver laced Wyandottes that should be female, but have decided to start crowing and being aggressive with the other birds. They are 5 months old now. I believe they are really Roos, but my wife is convinced otherwise. They have no spurs, but their comb is a bit larger than the other birds (including Wyandottes) that are at the same age. They do not try to mount the other birds. I have a few pics of one at https://picasaweb.google.com/ourpix...authkey=Gv1sRgCLul54zcua_i4gE&feat=directlink. The other one is the same, except no tail feathers. No matter what I have to find them a good home because we can't have crowing going on. But I sure am curious - what do you think?
