What breed is this?

[THolloway]

I received this chick to add to my coop today along with another Rhode Island Red chick and this looks like a mix to me. Could you please help me figure out what breed this chick is? Also I'm guessing that she is about 10 weeks old. Does that sound right? Thanks in advance!

My guess is mix.

Mixed breed. Where was she from? Probably has some game or Easter Egger in her
