Just curious, where did you hear that it was not the pigment in Marigold that helps brighten the legs?I haven't found a dealer for Show Gold in my area, so I've fed all my chicks Purina Chick starter. I contains Aztec Marigold, but I'm not sure of how much is in it. I wouldn't think color would matter, since it's the nutrients in Marigold, not the pigment, that helps brighten the legs.
