I'm going to pull a @casportpony and ask how his poop looks? is he eating good
casportpony is our resident member who is interested in poop because it can tell alot about our birds and how they are doing.
Are you sure this one is a drake? did you give them any niacin or Brewers yeast when they first started? When he walks does his legs shake or do they look bowlegged? Just trying to get an idea of what this could be other than the spots.
