Welsh Harlequin Duckling. (Any Guesses on Gender?) Pictures Included.

[Sundevill11]

Can anyone who has Welsh Harlequin's help me determine the gender on this duckling? Info on the internet says you can somewhat (70-90%) determine the sex by the bill color. This duckling is probably 6 days old and has a dark grey bill leading me to believe its a male. I tried sexting it but cannot see any evidence of male anatomy.

Adorable!

Yes, you can bill sex Welsh Harlequins but only for the first few days. After that the bills start to look the same as the other gender. Unfortunately its a bit late to bill sex your duckling here.
But once s/he is about 10 weeks old you can try voice sexing. Females start to quack loudly quite early on, and males will slowly develop a low and rashly frog-like voice. Around this time s/he will l start to get his adult feathers. Once s/he is fully feathered, you'll notice a curly tail feather if he's a drake. If she's a hen then the colors will look a bit different than a drake too.
