I know this is a stickky about this, but it much more about mallard derived ducks. So post up any ways(besides vent sexing) or tips of telling gender. It doesnt just have to be about ducklings, any age young or old. I am also wondering, are there any ways I can tell the gender of a 25 day old scovy orther than venting.
The males will start growing quite a bit faster than the females. And their Caruncle area will darken faster.
