Eggs – Why are Italian eggs so yellow

eggs

I've noticed when I've bought Italian eggs from delis here in Europe that the yolks are very yellow – almost orange. Why is this? Assume it's the hen's diet. What are they feeding chickens there?

Best Answer

Alternatively, the chickens may have been fed maize (corn); they market a specific maize-fed brand over here and the yokes of those eggs are a very deep yellow as well.
