Why does the yolk colour of an egg vary from a very light yellow colour to a bright yellow colour?
Egg yolk colour can range from pale yellow to deep orange. The type of feed influences the colour of the yolk. All feed is carefully balanced to ensure the laying hens are getting the vitamins and minerals they require for good health. Wheat-based feeds tend to produce a paler yolk colour while corn-based feeds produce a darker yolk colour. Geography, across Canada and across international borders, influences which grain dominates the feed ration and therefore the colour of the yolk. Yolk colour does not affect the flavour, nutritive value or quality of the egg.
