What/how do you go about feeding your Scovies when they are in a mixed age flock? I have 3 adult ducks w/ducklings that I've just started on 16% duck feed after feeding them 20% chick-starter for two weeks & adding extra niacin to their diet. We want to move our last duck & our drake over w/them as soon as Gwen's ducklings hatch otherwise it will be a bear to gather them up fm all over the chicken yard. Our duck feed says "good for ducklings fm 2 weeks to adult. I'm trying to avoid angel wing in the ducklings but want to be sure the new ducklings get a good healthy start. Thanks for your help!
