you mean chocolate barred
Brown duckling, much bigger than the others. I think its a drake.
It's hard to see in photo but this one has peachy orange tone on head chest and belly, with gray (lavender???) tail and lower back feathers. This was a very light tan wild type duckling when born. Could this be a buff? The one to the right of it is coming in all gray with a white bib and head. I've only had one silver, and my silver seemed more streaky than this gray. The seller I bought eggs from said lavender was a possible outcome.
the duckling standing on right facing camera, directly in front of the blue and white mom, has gray and tan feathers edged in white. Maybe a lilac barred?
most are brown barred, looks black in photo. they have changed a lot.
