Yep, the chicks I bought were definitely Russian Orloffs and not spangled hamburgs. Now that they are about 6 weeks old it's pretty obvious that the feedstore had them labeled incorrectly.
I was bummed out at first, but we've grown pretty attached to them and they are turning out quite pretty. We've named them Sonia and Sasha, though we don't know if they are hens or roosters yet. we bought them from a bin labeled "Gold Spangled Hamburg Pullets." The breed part was obviously wrong, but hopefully they are at least pullets.
I don't know how to tell the sex with this breed...they don't seem to have any comb at all, just a tiny flat spot on the forehead with no feathers.
For a while I wasn't sure what color they were going to be either because the spangled Orloffs that I saw in pics had lots of white on them, but mine did not have any white feathers at all. They were just a pretty dark mahogany color with darker markings here and there. Now they are finally starting to get the white splotches, so I guess they are the spangled color.
