That is where you are mistaken. The bacteria and possible dog medication (anti-flea or dewormer etc.) can and will very well enter the egg as well. Salmonella for instance also transfers to the eggs.Good thing only the flavor transfers to the yolk, not the actual poo. GC
Excellent reply. What makes the yolks extraordinarily orange? the poop inside the insects they eat. Are other animals into it? Yes, most omnivores. Pigs really favor fresh manure, bother nearby cows for fresh meals (don't ask), and can live and thrive solely out of fresh manure. Crows/ravens too, and of course any large predator, because after each kill they go straight for the gut.The secret ingredient that makes free range eggs taste so much better. Enjoy.
