There was a topic on this board a while back about goats giving chickens worms. I asked a state poultry vet about it, and he said they don't share worms because different species effect them both. In fact, I remember that some pastured livestock raisers used chickens to control worms on pasture for goats, cows, sheep, and similar. They would follow the chickens after the other animals and the chickens would eat worms out of the feces.

The only exception is the "racoon roundworm," which can effect dogs and cats and goats and more, too. If they get it, the worm discovers it's in a foreign host so it tries to migrate to tissue it recognizes. Since the brain is so primal, that's where it goes as it considers it the closest thing to "familiar tissue." And then it kills them. He said it's not a flockwide problem, though. He said to keep raccoons out of the chicken run (there are more good reasons for that!).
