We acquired 6 baby ducks and have been keeping them on our bathtub with 3 water dishes, a grit dish and a feeder. There is only 6 baby ducks in a large bathtub. They have food and water constantly and get nutritional yeast supplement as well daily. They are now approx 4 weeks old. I had noticed the past week that one of the khaki Campbell's was pecking at the other ducks, mainly when swimming and during bath time. However the last 24 hours has gotten much worse and we woke to both our blond runners with raw bald spots on their tails from the pecking KC. We have since separated the pecking duckling from the rest and are wondering if there is any way to solve the issue or if we will need to get rid of the pecking duck?
