Oh, I can second the recommendation on SS! My roo is SS, and I have two hens, they are lovely. Excellent foragers, and the first ones there if you are weeding. They do need to examine each thing you pull up and the hole it came from...they don't help in the speed weeding category. There is a bit of the blue green sheen on the black bits of their feathers, and the roo has lot of it.
