We got our first ducklings (8 of them....couldn't resist they were all so cute) at TS about 6 weeks ago. We have been able to figure out what types all are except these two. They are the biggest of the group (even bigger then the 2 pekins). The one on the left was solid black as a baby so we assumed Cayuga but as he feathered out it became apparent that he isn't. The one on the right has a ring around his throat area and white markings on his wing with a stripe of blue feathers. Their backs look very similar to our Khaki (lace like markings) but they are MUCH bigger and much darker. I am guessing Hybrids of some kind... and ideas??
