Hey Walt, as an Aussie, a "roo" to me is still a Kangaroo
That said, please educate me on the correct terminology. I have always used "hen" and "rooster" to differentiate female from male, with "pullet" and "cockerel" indicating they are young birds of those same genders. I think of "Cock" as the British term for "Rooster", (although it clearly was an American term when the Wright Brothers were having their heydey, since "cockpit" derives from "cock" for "male" because the early pilots were all males...but I digress). I figured it went out of style to use the term "cock" here because the word now has other meanings. Are you saying that "rooster" is NOT the correct terminology for an adult male chicken?
