Any guesses on this chicken

[Piper25]

We’ve had this chicken since she was a few weeks old. She is little over a year old now. She never laid an egg til she was 44 weeks old. Her eggs are are a large, light brown, more rounded than oval. We got her from a farm down the road. Just wondering if anyone would know what mix she is. We also have three 10 week old chicks we bring outside in a dog crate, the white chicken will walk around and around the cage for half an hour trying to peck at the young ones, whereas our barred rock will look at the chicks, then move on to do her own thing.

Obviously mixed breed. Most probably with Rock.
