O.K so I took a rockX in as a favor, yes I know I am a sucker. I also toook in a pekin duck. I had been told the rock X was a female, although she has a pronounced comb, but otherwise no more male physical charecteristics. however, she and the duck have bonded, and now she mounts the duck and acts out copulation. So now it is interspeciel same sex union. Anyone have a theory as to why?
