SUMMARY—The deposition of the pigments of Aztec marigold petal was determined in the egg and tissue of laying hens fed 33–66 and 99 mg of the pigments per kg of low pigment diet. Thirty‐three mg pigment per kg of feed produced yolk color which is considered acceptable to the consumer. With an increase in the amount of pigment in the feed, color deposition in the organs increased, but efficiency of utilization was lowered.
