It is a little hard to tell from the pic and not knowing how old it is. It could be a mix or maybe it looks like an Old English Game hen? Wyandottes have a rose comb, that is one tell tale sign. If you have already, take a look at the breeds chart (click at top of screen). It has lots of cool pics for comparison.
It's shaped like a Wyandotte. Looks just like mine and mine is 10 weeks old. I'm pretty sure you have a silver laced. Lacing is poor due to hatchery quality. My Wyandotte is the sweetest chick ever!
