Our order was supposed to have 3 red and 3 gold sex links. It does look like 3 look alike and the other 3 look alike. They don't look a lot different though, but 3 have dark on their heads. So anyway now they are getting a lot of wing feathers, and 4 of them have colored feathers and 2 have white. Is that normal? Is it possible the 2 with white wings are roos? I thought sex links were a sure thing as far as sexing...
