My grandfather bought me 6 crested ducklings from a local farmers market back in May. I had them for about a month when I became ill and was admitted into the hospital with the Campylobacter bacteria. I figured out that it had to have been from the ducks so I took them to my grandfathers farm where they would have a pond. This was great for them until my grandfather's goats started dying.. We know the ducks are the cause but don't want to get rid of them. However, we cant have them contaminating the water that the other animals drink.. Is there a way to treat the ducks so I can still keep them??
