To answer the original question: a roundworm might pass through a chicken's oviduct into her egg, but it's not possible to get a roundworm infection (or paratization?) by eating a roundworm. You could eat a raw roundworm salad and be just fine. One gets roundworms by eating roundworm eggs, which commonly occur in dirt. Also, from what I understand, there are different species of roundworms, and those that parasitize birds don't live in humans. Has anyone here actually found a worm in their chicken's egg? That would be totally grooooossssss....
