Out of 10 ducklings there is only one still alive. All the symptoms fit duck hepatitis. One minute they are fine and then the next they are lethargic then twitching/ seizing and dying. It is awful! Is there any way to help the last duckling? It is breaking my heart thinking that she is doomed! This has been the worst experience ever and I won't get another duckling as long as I live. Is there anything I can do? Please help!
