Sexing Silver Appleyard Ducks

[MissPrissy]

I need help learning how to visually sex appleyard ducks. I only have one with a tail curl. I have several with all dark heads. I'll get photos later but everything is so mucky and muddy and the ducks are dirty - just a mess right now.

Should I try to vent sex? Look for the noodle (as terrie would say)?
