What is my duckling?!

[mccombs]

Hello!
I just wondered if anyone can hazard a guess as to what Donald Duck might be? I hatched him from a clutch that were supposed to be crested call eggs, but as he grows I'm getting less and less convinced that this is what he is!
He's developed brown feathers on his wings and his head has a brown stripe down the middle, he's a bit of a mystery! I've included a photo of him as a baby, and now at 5 weeks old with his Runner buddies Jack and Vera!

He looks call to me, I dont see they crest, however have you ever read up on it? Its a deformity in the ducks skull

I just wanted to note that this duck's brown color on the wings may be a sign that it is a female. Just my opinion.
