The feathers just keep coming in. You can see how much brown and beige coloring they are getting. I'm not sure exactly how large they will eventually get, but they seem to be nearly the size of adult ducks to me.
This appears to be a female, and it looks like she's a crested duck. She'll be almost as funny looking as the runner duck with that puff-ball on her head.
See all the funny feathers just starting to poke through around their faces? Right now they look a little bit like a pin cushion. I can't wait to see the final result.
