first the closer the color of yolk is to red the better it is for some purposes, such as pasta, but does not necessarily make it better, though most "chefs" will say try to get an orange egg yolks
second, theres no difference free range vs caged
take the cubic feet of the cages thta contain 100 chickens, add it together, it will equal the cubic feet that 100 "free range" chickens get
its the same shit, just a marketing ploy
