So, I have had this crested duckling (we call him Moe-short for Mohawk) 1 week tomorrow. He (or she) has gotten increasingly dark every day and has a "dirty" look in its head and back. It was in with the "assorted" unsexed ducklings at Tractor Supply Company. I assumed it was just a white pecking with a crest but I've been looking for pics and haven't seen what one with his markings looks like as an adult. Any ideas. Also, is my darkest duckling a Swedish? He (or she) is the sweetest one of all. It lets us hold it without fussing like the others and is the smallest though I believe they all hatched the same day. I noticed its stance looks more like an emu than a duckling (not so large chested and leaning forward like the others-like the runner ducks). Anyway, I could wait and see in a few months but I like seeing what others have to offer. In the top pic the one to the farthest left just has mud on his chest. The mysteries are pirate duck Jeffrey and Moe.
