Sorry about the loss of your duck. Wow they are pretty though! I wonder if they will look like my female, Jeepers, when they molt; they look much darker right now. I can't remember what Jeepers looked like before getting her adult feathers. It's been a year lolThe breed standard states the female should have a dark bill, however not all birds meet the standard. I ordered 4 WH females from Metzer last August. Before this weekend I would have said they are all happy and healthy. Unfortunately I lost one this past weekend. There was no clear cause of death but the vet suspects she had a congenital issue. I don't want this to turn you off Metzer though. I don't think they can be blamed for her sudden death and getting the same ducks from another source would run the same risks. Pure breed animals are far more susceptible to these issues as they are inherently partially inbreed. All that being said, I love my ducks from Metzer. Here is my most recent picture of them. Keep in mind they haven't gone through their second molt so they still have their juvenile feathers.
