She was pretty camera shy, but here are some pics of my hen Agate. She has the distinction of being my biggest hen, and the one with the fluffiest bloomers. Very similar shape to my silver-laced wyandotte, but her legs are definitely not yellow--more of dark grey/slate color, and her comb is flat and smooth. Local feed store called them blue wyandottes, but I'm sure it's possible they are some kind of mix--probably not the breed standard. But they are very pretty.
I believe my girl will look just like yours. Probably some kind of mutt Wyandott which is perfectly fine with me! Thanks for the pictures!
