What were you feeding them? Just the Purina? All mine have done great on the Purina duck pretty much exclusively. Last year I was reducing the protein by cutting the feed with oats per Dave Holderread's advice. This year my ducklings didn't get any oats and they've done fine.
You'll probably find some conflicting info on the subject. A lot of people on here swear by a high protein diet. Honestly the conversation can get a bit contentious.
