I emailed the seller and she said he was part or all rouen/muscovy/runner.
He has a banty chick with him. She follows the duck around everywhere! And usually they sleep next to each other under the hen I know that ducks are very social- will she be a good friend?
Also, we bought medicated chick starter; but I read that feeding that to a duck is a big NO-NO. They don't have duck feed at the feed store. Suggestions?
