Wilcox Farm egg yolks - how do they do it?

Did you use same amount of duck eggs for chickens eggs?

If a cake recipe calls for three chicken eggs, you can use two duck eggs.
You can use the same amount, and the cake will be richer (and slightly taller).
In cornbread, I will use one duck egg in place of the chicken egg.

Lol Really? Did you see the attached pic? Those yolks were almost red! I've never seen yolks that color before especially not from the grocery store.

Yes I saw the pic. I wouldn't eat those. Too strange looking for me. I like my yolks to look like yolks.

Sometimes duck egg yolks can have a greenish tint.
This is just the chlorophyll from eating grass and greens along with their feed.
They taste perfectly fine.

They feed them dyes to color the egg yolk. They can be natural dyes or more often, synthetic dyes.
Some of my free range chickens do lay eggs that color, some even darker, but not all year round because some carotenoid-rich herbs and fruits are seasonal.
