That's a she and definitely not a Wyandotte. If she is, she's the poorest quality Wyandotte I've ever seen, sorry. (and I'm talking about body shape before color)
About the age, not 100% sure as the people I got them from were a little weird lol, they called them "July lil one" so some may be 8+ weeks, some may not be
Oh and don't apologize for saying I have a mutt lol, no offense taken as I kinda figured that's what I was dealing with
I ended up selling 10 of my banties today to "thin the herd" so to speak lol, I kept this lil one as I kinda like it lol
Its weird how orange the legs look in pics when in person they are kinda white? I will try to get a picture to show what I am talking about but its kinda hard to explain lol
