At least I think it's a white crested blue polish... this is my first one and based on the coloring and what I could find online, that's what I'm thinking it is (correct me if I am wrong). I don't know the age, but the seller believed it to be about 8 weeks. It's still pretty small. Any guess on gender? He had one other that I think was a white crested black. He said if this one turned out to be a roo he'd let me bring it back and swap it for something else. The other polish looked to have the same shape of crest though. I know they're hard to tell.
