Ok, I got "Blacky" picked up and separated. The loud quacking in the background are my 2 females offended that I picked this one up. I tried to walk away and they followed lol. I currently have 2 females and 1 male, I'm pretty sure. This one is about 4 days younger than the rest. So still not sure. Maybe his little peep/quack is too young still. Pics are of them all to show how big Gerald our drake (white bigger one) is compared to the rest and he definitely is more of a whisper.
Here is the video of Blacky:
