foods for yolk color

[wundernurse]

What are some foods that make the yolks a nice yellow/orange color? My birds get soy-free layer feed, some BOSS, and lots of other fruits and veggies in a addition to some free ranging. I don't want to give them anything artificial, just some treats that add some rich color to the yolks. Thanks

Beta carotene rich foods are what give the nice orange color. Corn does some too.
If they are free ranging you should already be getting the orange yolks?
