This, I seriously do not get. Why would anyone want eggs from chickens that were not fed with "animal by-products"? Certainly not the folks who don't want animal by-products themselves... that what eggs ARE! Not to mention the fact that these eggs, along with the "organic" eggs, the "free-range" eggs and the "no cage" eggs are all like $1.50 more per dozen. Presumably because there's so much more labor to collect the eggs from where the hens are hiding them...
