In case it's not clear, that is a baby duck of some sort, either a domestic Mallard derivative, or possibly Muscovy. I'd say maybe 3 weeks old? It's got a lot of baby fuzz and the tiny baby wings. It'll grow like a weed for the next few weeks. It can eat a basic chick starter that doesn't have antibiotic medications in it with the addition of a niacin supplement (I use brewer's yeast, toss a little on top when you feed). It will love chopped greens and veggies as treats. Also, the suggestion to get it a companion is a good one, ducks are not happy by themselves. It's sure a little cutie, I wonder how it got out by itself? Maybe someone is really looking for it? If I lost a duckling, I'd be pretty upset.
