I have an 12 week old hen/rooster/he/she the can not ,will not ,make up its mind. It doesn't have the saddle feathers, it's comb is considerably smaller than the other 2 roosters its age, and it hasn't crowed yet. It isn't developing spurs while my two known roos have. It does have a roo-ish looking tail and it's comb is pretty red. We're thinking it is a Australorp. It was a free, grab bag chick.
