Wyandotte? From Barnyard Mix

[ILoveMyBarnyardChicks]

The folks who sold me her said maybe an ISA brown, but as she grows, I don't think that's right. I am new to chickens in general and have pretty solid ID's for everyone else in the flock, but I'm stumped on this girl. Maybe just a Wyandotte mix?
Also yes, that is hardware cloth layered on top of chicken wire, after I learned that it is not sufficient to protect a run on its own. (Thanks to this forum!)

It has a single comb, so I don't think it is a Wyandotte mix. It's some type of cross, though. Looks pretty similar to a black sex link, but could be a mix of anything the seller had in the flock.

I hadn't looked at these before- They look super similar. Thank you so much!
