I actually just read today that both male and female get the green heads and it's not until adult hood that the males becomes more vibrant and the females fades away. As for sexing by feathers I think you have to wait for the drake feather to curl at the tail to know if it's a male. What do their quacks sound like? May not be a fool proof method but does seem to work out in most cases. The female will quack and the male will not. Look up sexing ducks by voice.Thanks! :/
Our ducks are 11 weeks old today. They have been shedding their adolescent feathers for couple of weeks. Today, we noticed green starting to develops on their heads. We thought we had 2 hens, instead they may be drakes. The green doesn't show up in pics or I would post some.
Can anyone tell me how to tell hen vs. drake feathers without waiting?
