I do not believe that is a polish. I do not see a vaulted skull for one thing, and it looks nothing like the polish I've had. OP, can you show a photo that includes the chick standing up? Preferably both a full-body profile and a face shot.
well, the leg color tells me it could be polish, but there is no defined 'poof' at the top of the head like polish should get. not all polish get the skull poof btw (my Chickie didn't have one)! usually the bigger the poof as a chick the bigger/better the poof as an adult! i can tell you the color is probably going to be golden!
