Thank you for all of the responses! I have never been able to say he is XXX breed because he looks different from most pictures I have seen.
Aside from appearance there is good evidence that Randy is at least part red sex link:
-Randy is extremely cold intolerant. In the extremely mild South...
My grandmother came back from an agricultural market one day, with a beautiful orchid plant the size of a small tree and little brown paper bag that was chirping... I honestly have no idea where he came from other than he was purchased in a (flee market style) agricultural market.
What breed is my rooster?. He weighs approximately 5-6 pounds, is 5 years old, and crows loudly. The black patch on the back of his neck is just dirt and Vaseline leftover from recent cold fronts.
