Voice sexing

[Miss Ducky]

One of my (approximately) 2-week old ducklings began to quack last night. I was wondering if one gender begins to quack before the other, as the other two have shown no sign of it. So, duck experts, what do you think?

I had one start with 4 weeks. Now my 7 week old ones finally show their true voices. Some started when they were 6 weeks old. I think 2 weeks my be a little bit early to tell. Only time will tell. They all should have their true voices by the time they are 8 weeks old.
