Does yolk colour affect egg quality, flavour or nutrition?
No. The colour of the yolk is influenced by the hen's diet and is not an indicator of freshness and has no significant influence on nutrition or flavour.
Specifically it is from free range pasture rich in Xanthophylls, which are yellow pigments from the carotenoid group. Xanthophylls is literally Greek for yellow. As we cannot depend on pasture alone to deliver a consistent yolk colour, we also include very low levels of natural plants extracts derived from Marigold petals and Paprika in their diet. This is not intended to create a false colour, but simply to achieve a more even result. These extracts contain the same natural Xanthophylls (lutein) that would normally colour the egg yolk.
But our hens are not machines, so there will always be variations in yolk colour that are beyond our control. What's important is that their diet is regularly monitored to achieve the best nutrition for the hens. And in turn you can enjoy nutritious healthy free range eggs.
