I used to buy eggs from a local farm whose chickens would always lay brown and deep auburn eggs (like the colors on either end of this photo). I swear, those chickens were on a better diet than I was. Whenever I cracked into one of those vibrant shells, the yolk was no exaggeration blood orange. Like some of the yolks were even so deep they were more red than orange. I miss those eggs, the best I have ever had.
