i usually purchase free run omega 3 eggs from central fresh market. pricey. but a wonderful yolk which has more yellow colour than most.
i saw some eggs on sale the other day, $2.99(CDN)for 18 eggs. so i bought them. the yolk lacks yellow. scrambling them and you can really see that they are very bland in colour. also boiled, they taste bland. fuhgetaboutthem.
