I have had three male magpie ducks for almost a year. The three ducks have been inseparable since we got them. They live by our pond and have plenty of space to be away from each other, but they were always huddled together since the day we got them. They made through a tough winter, and about 3 weeks ago we went to feed them in the morning and one duck was missing. We figured a predator got him to we moved the other two to a cage by the house and immediately, the two males began fighting violently and we separated them. The next day, we found the missing duck in the yard. He was dead and his chest was pecked apart (from the other ducks). It's been almost a month and we still cannot have the other two males together or they immediately go crazy fighting. What do I do?!?! Has anyone seen this before??
