Carlton was an only chick born with 5 ducks and a goose. How do you convince a chicken he is indeed a chicken, and not a duck? ** few weeks ago ** few weeks before that ** younger ** when we brought them home Yes.. He's a duck. He spends every rainy day soaked to the skin just to hang with his girls. He mates them. He does not roost. Been told we should have called him Chuck (because he's part chicken, part duck).
