I was given 6 hens and was told they are RIR's; one is a deep rich copper color and she is lowest in the pecking order yet biggest in size and most tame, she loves to be held; the other 5 are lighter in color with some varigation mostly at the tips of their feathers, they look like the pictures of the Red Sex Link, anyway to know for sure? Also is Red Comets another name for Red Sex Link?
