I know hens usually don't crow unless there's no rooster present. I have two 12 week old bantams, a d'uccle roo and a wyandotte pullet. I think my "pullet" tried to crow today with the rooster standing next to her. He had been crowing for a while and then suddenly she let out a crow, it wasn't perfect but she was definitely trying to crow. She only did it twice in a row, then no more. Could she really be a rooster?
Here's some pictures of "her" :
