Hello! I'm starting to plan for ducks that I will get in the fall, but I had a few questions. We have a small man made pond (I assume it was intended for livestock), and I wondered if it was safe for ducks to swim in. It's currently green with algae, but I've researched barley straw treatments and water plants and things like that. My concern, though, is about bacteria. Could a stagnant pond cause e coli, botulism, or something of that ilk? Or, would it only affect eggs laid in the water? Is there a way to test your water? If it is an issue, how do you keep them out of the pond?
