So I have just started keeping ducks. I successfully hatched 9 last September. A week ago today I found one of my ducks dead (and half eaten) by the feeder. I keep my ducks with my chickens. It was a male so I thought maybe the males started fighting and then the chickens stred pecking him. Today I found one of my female ducks in the same place very weak and she died 30 minutes later. No obvious signs on what could be wrong?. Can ducks over eat? All other chickens and ducks seem healthy. Any ideas? Thank you.
