Male or female

It's really too early to be positive. I would guess duck because of the beak color.

 

Can you post a video of it "talking"

 

Well if there is a quack then it is def a girl.

 

Yes you can do it two ways...make an account here https://vimeo.com/

after uploading a video to the Vimeo either copy and past the link here OR click the insert video button (next to the insert picture button) and past the link in there.

 

Hard to tell as he/she is pretty young yet...there might be a little female sound coming. I would guess in the next week or two you will really be able to tell.
