Male or Female Welsh Harlequin duckling?

[JayLavinder]

Is this a female or male welsh harlequin? I'm a bit confused as to the sex of this one because this duckling seems to be half and half with a dark line down the center? Can anyone help? This duckling is 2 hours old. Thanks!

Don’t rely on bill color to sex your ducklings. Vent sexing is the only accurate method for sexing ducklings.
