Yolk color changing experiments!!

[cluck queen]

Hello all!!!

I have recently seen online that a Japanese restaurant has sold eggs with different colors of yolk! Some ranging from red to even WHITE!!! How exciting! Has anyone made such colored yolks? I know it has to do with feed being offered. My question is, is what are you able to feed to achieve such different colored yolks? Please feel free to post your photos!

"Red" is from food high in beta carotene/vitamin A, white is the lack of beta-carotene/A, it actually isn't healthy for the bird.

I'd like to make white yolks. I'm sure there is a way to make it healthy and also achieve this color.

I have a buddy who grew eggs and meat for someone who is deathly allergic to corn.
They fed a corn free feed(all I know about it) and the egg yolks were white.

Color tells you the nutritional content of the feed. Marigolds turn yolks white because they give more nutrients to the chicken. White? I can't imagine when they are feeding the girls.

Unfortunately that is folklore and not true.

Marigolds turn yolks deeper yellow.

Harvard University:

Red: Rich in the carotenoid lycopene
Orange and yellow: Provide beta cryptothanxin
Green: sulforaphane, isothiocyanates, and indoles
Blue and purple: anthocyanins

Just saying, synthetic dyes aren't the only things that put color in our food.

I happened to be watching the Japanese channel NHK one night and they were interviewing a chicken farmer that fed his chickens red chili peppers. I’m pretty sure it was in a mash.
