Stray chicken

Hello!

I’m looking for advice. The universe has recently gifted me this chicken. I went out one day and she had moved in and lives under my house (for now, I plan to give her a proper coop). Is it possible to tell when kind of chicken she is and if she’s egg laying by just these pictures. I want to make sure I give her the right feed and care she needs!
Also I have tried to find her original owners but not neighbours have come forward. I live on a main road and she may have been dumped.

Also her name is Hennifer clawerence
