Well, in the past three days, I've lost two ducklings. Today, Inky had a heart attack and died. There was nothing anyone could do. This evening, my harlequin started sticking one wing straight out. It's very strange. I don't get what she's doing. She's only 3 weeks old. Barely started feathering. She just sticks it straight out. Sometimes, she does it with both wings. Any idea what this could be? I'm worried because earlier today, Inky just acted suddenly tired, then had seizures, before she eventually passed away. I don't want something else to happen. To lose 3 of my ducks in three days, that would be terrible. Thank you for any input you can give!
