For a while now we've been getting green yolks from a certain chicken. I don't know which chicken but the eggs that always have the green yolk seem to have a little swirl in them. Does anyone know what causes this? I've tried to look it up and i've read that cotton seed oil can change them. But they haven't been near anything like that and it seems like its only one chicken that lays the green yolk. They do get to free range for a couple of hours a day.
Also the green egg yolk doesn't smell but seems a little tougher than a regular egg yolk. I can't bring myself to taste it and see if it tastes normal though.
We try to set aside they eggs that we think hold the green yolk because we sell eggs every once and a while and i don't want anyone to get a green yolk!
Here it is (dont mind all the little bits in the white, its jsut bread crumbs)
