Kari ~ I don't have any pics right now, but "mossy" refers to too much red/copper coloring in places it should not be. Like on roos, too much (more than 10%) red on the breast, or elsewhere. On hens, the mossy can come as a type of fuzzy brownish color bleeding through the black on the back or breast. Hens should only have coppering on their hackles and a small colloar around the front of the neck, not extending to the breast. The mossy could probably show up anywhere on the body, but these are the most common forms I've seen. Others may have another opinion.
