What can hens be fed so the eggs will contain yolks with exotic colors, i.e. red, green, etc.?
Fat soluble dyes, such as Sudan III (red), Sudan Black (green-black), Scarlet B fat (red), and Eliziran Green can be given to hens to cause brightly colored egg yolks. Twenty to forty grams per day administered orally via soluble gelatin capsules will result in the desired colored yolks in 6-8 days. These dyes are available from biological supply houses. But, please don’t sell or eat the eggs – it is illegal!
